GENERAL DESCRIPTION
The AD9714/AD9715/AD9716/AD9717 are pin-compatible,
dual, 8-/10-/12-/14-bit, low power digital-to-analog converters
(DACs) that provide a sample rate of 125 MSPS. These TxDAC®
converters are optimized for the transmit signal path of commu-
nication systems. All the devices share the same interface, package,
and pinout, providing an upward or downward component
selection path based on performance, resolution, and cost.
The AD9714/AD9715/AD9716/AD9717 offer exceptional ac and
dc performance and support update rates up to 125 MSPS.
The flexible power supply operating range of 1.8 V to 3.3 V and
low power dissipation of the AD9714/AD9715/AD9716/AD9717
make them well-suited for portable and low power applications.
PRODUCT HIGHLIGHTS
1. Low Power.
DACs operate on a single 1.8 V to 3.3 V supply; total power
consumption reduces to 35 mW at 125 MSPS with a 1.8 V
supply. Sleep and power-down modes are provided for low
power idle periods.
2. CMOS Clock Input.
High speed, single-ended CMOS clock input supports a
125 MSPS conversion rate.
3. Easy Interfacing to Other Components.
Adjustable output common mode from 0 V to 1.2 V allows
easy interfacing to other components that accept common-
mode levels greater than 0 V.

TERMINOLOGY
Linearity Error or Integral Nonlinearity (INL)
Linearity error is defined as the maximum deviation of the
actual analog output from the ideal output, determined by
a straight line drawn from zero scale to full scale.
Differential Nonlinearity (DNL)
DNL is the measure of the variation in analog value, normalized
to full scale, associated with a 1 LSB change in digital input code.
Monotonicity
A DAC is monotonic if the output either increases or remains
constant as the digital input increases.
Offset Error
Offset error is the deviation of the output current from the
ideal of zero. For IOUTP, 0 mA output is expected when the
inputs are all 0. For IOUTN, 0 mA output is expected when all
inputs are set to 1.
Gain Error
Gain error is the difference between the actual and the ideal
output span. The actual span is determined by the difference
between the output when all inputs are set to 1 and the output
when all inputs are set to 0.
Output Compliance Range
Output compliance range is the range of allowable voltage at
the output of a current-output DAC. Operation beyond the
maximum compliance limits can cause either output stage
saturation or breakdown, resulting in nonlinear performance.
Temperature Drift
Temperature drift is specified as the maximum change from
the ambient value (25°C) to the value at either TMIN or TMAX.
For offset and gain drift, the drift is reported in ppm of full-
scale range per degree Celsius (ppm FSR/°C). For reference
drift, the drift is reported in parts per million per degree
Celsius (ppm/°C).
Power Supply Rejection
Power supply rejection is the maximum change in the full-scale
output as the supplies are varied from minimum to maximum
specified voltages.
Settling Time
Settling time is the time required for the output to reach and
remain within a specified error band around its final value,
measured from the start of the output transition.
Spurious Free Dynamic Range (SFDR)
SFDR is the difference, in decibels (dB), between the peak
amplitude of the output signal and the peak spurious signal
between dc and the frequency equal to half the input data rate.
Total Harmonic Distortion (THD)
THD is the ratio of the rms sum of the first six harmonic
components to the rms value of the measured fundamental.
It is expressed as a percentage or in decibels.
Signal-to-Noise Ratio (SNR)
SNR is the ratio of the rms value of the measured output signal
to the rms sum of all other spectral components below the
Nyquist frequency, excluding the first six harmonics and dc.
The value for SNR is expressed in decibels (dB).
Adjacent Channel Leakage Ratio (ACLR)
ACLR is the ratio in decibels relative to the carrier (dBc)
between the measured power within a channel relative to its
adjacent channel.
Complex Image Rejection
In a traditional two-part upconversion, two images are created
around the second IF frequency. These images have the effect of
wasting transmitter power and system bandwidth. By placing
the real part of a second complex modulator in series with the
first complex modulator, either the upper or lower frequency
image near the second IF can be rejected.

Figure 84. Simplified Block Diagram
Figure 84 shows a simplified block diagram of the AD9714/
AD9715/AD9716/AD9717 that consists of two DACs, digital
control logic, and a full-scale output current control. Each DAC
contains a PMOS current source array capable of providing a
nominal full-scale current (IxOUTFS) of 2 mA and a maximum of
4 mA. The arrays are divided into 31 equal currents that make
up the five most significant bits (MSBs). The next four bits, or
middle bits, consist of 15 equal current sources whose value is
1/16 of an MSB current source. The remaining LSBs are binary
weighted fractions of the current sources of the middle bits.
Implementing the middle and lower bits with current sources,
instead of an R-2R ladder, enhances its dynamic performance
for multitone or low amplitude signals and helps maintain the
high output impedance of the DACs (that is, >200 MΩ).
All of these current sources are switched to one or the other
of the two output nodes (IOUTP or IOUTN) via PMOS differential
current switches. The switches are based on the architecture that
was pioneered in the AD976x family, with further refinements
to reduce distortion contributed by the switching transient. This
switch architecture also reduces various timing errors and
provides matching complementary drive signals to the inputs
of the differential current switches.
The analog and digital I/O sections of the AD9714/AD9715/
AD9716/AD9717 have separate power supply inputs (AVDD and
DVDDIO) that can operate independently over a 1.8 V to 3.3 V
range. The core digital section requires 1.8 V. An optional on-chip
LDO is provided for DVDDIO supplies greater than 1.8 V, or the
1.8 V can be supplied directly through DVDD. A 1.0 µF bypass
capacitor at DVDD (Pin 7) is required when using the LDO.
The core is capable of operating at a rate of up to 125 MSPS. It
consists of edge-triggered latches and the segment decoding logic
circuitry. The analog section includes PMOS current sources,
associated differential switches, a 1.0 V band gap voltage
reference, and a reference control amplifier.
Each DAC full-scale output current is regulated by the reference
control amplifier and can be set from 1 mA to 4 mA via an external
resistor, xRSET, connected to its full-scale adjust pin (FSADJx).
The external resistor, in combination with both the reference
control amplifier and voltage reference, VREFIO, sets the reference
current, IxREF, which is replicated to the segmented current sources
with the proper scaling factor. The full-scale current, IxOUTFS, is
32 × IxREF.
Optional on-chip xRSET resistors are provided that can be pro-
grammed between a nominal value of 8to 32(4 mA to
1 mA IxOUTFS, respectively).
The AD9714/AD9715/AD9716/AD9717 provide the option of
setting the output common mode to a value other than AVSS
via the output common-mode pins (CMLI and CMLQ). This
facilitates directly interfacing the output of the AD9714/AD9715/
AD9716/AD9717 to components that require common-mode
levels greater than 0 V.

SERIAL PERIPHERAL INTERFACE (SPI)
The serial port of the AD9714/AD9715/AD9716/AD9717 is a
flexible, synchronous serial communications port that allows easy
interfacing to many industry-standard microcontrollers and
microprocessors. The serial I/O is compatible with most synchron-
ous transfer formats, including both the Motorola SPI and Intel®
SSR protocols. The interface allows read/write access to all registers
that configure the AD9714/AD9715/AD9716/AD9717. Single or
multiple byte transfers are supported, as well as MSB first or
LSB first transfer formats. The serial interface port of the AD9714/
AD9715/AD9716/AD9717 is configured as a single I/O pin on
the SDIO pin.
GENERAL OPERATION OF THE SERIAL INTERFACE
There are two phases to a communications cycle on the AD9714/
AD9715/AD9716/AD9717. Phase 1 is the instruction cycle, which
is the writing of an instruction byte into the AD9714/AD9715/
AD9716/AD9717, coinciding with the first eight SCLK rising
edges. In Phase 2, the instruction byte provides the serial port
controller of the AD9714/AD9715/AD9716/AD9717 with infor-
mation regarding the data transfer cycle. The Phase 1 instruction
byte defines whether the upcoming data transfer is a read or write,
the number of bytes in the data transfer, and the starting register
address for the first byte of the data transfer. The first eight SCLK
rising edges of each communication cycle are used to write the
instruction byte into the AD9714/AD9715/AD9716/AD9717.
A Logic 1 on Pin 35 (RESET/PINMD), followed by a Logic 0,
resets the SPI port timing to the initial state of the instruction
cycle. This is true regardless of the present state of the internal
registers or the other signal levels present at the inputs to the
SPI port. If the SPI port is in the midst of an instruction cycle
or a data transfer cycle, none of the present data is written.
The remaining SCLK edges are for Phase 2 of the communication
cycle. Phase 2 is the actual data transfer between the AD9714/
AD9715/AD9716/AD9717 and the system controller. Phase 2 of
the communication cycle is a transfer of one, two, three, or four
data bytes, as determined by the instruction byte. Using one multi-
byte transfer is the preferred method. Single-byte data transfers
are useful to reduce CPU overhead when register access requires
one byte only. Registers change immediately upon writing to the
last bit of each transfer byte.

R/W N1 N0 A4 A3 A2 A1 A0
R/W (Bit 7 of the instruction byte) determines whether a read or a
write data transfer occurs after the instruction byte write. Logic 1
indicates a read operation. Logic 0 indicates a write operation.
N1 and N0 (Bit 6 and Bit 5 of the instruction byte) determine the
number of bytes to be transferred during the data transfer cycle.
The bit decodes are shown in Table 12.

Description
0 0 Transfer 1 byte
0 1 Transfer 2 bytes
1 0 Transfer 3 bytes
1 1 Transfer 4 bytes
A4, A3, A2, A1, and A0 (Bit 4, Bit 3, Bit 2, Bit 1, and Bit 0 of the
instruction byte) determine which register is accessed during the
data transfer portion of the communications cycle. For multi-
byte transfers, this address is the starting byte address. The
following register addresses are generated internally by the
AD9714/AD9715/AD9716/AD9717, based on the LSBFIRST bit
(Register 0x00, Bit 6).
SERIAL INTERFACE PORT PIN DESCRIPTIONS
SCLKSerial Clock
The serial clock pin is used to synchronize data to and from the
AD9714/AD9715/AD9716/AD9717 and to run the internal state
machines. The SCLK maximum frequency is 20 MHz. All data
input to the AD9714/AD9715/AD9716/AD9717 is registered on
the rising edge of SCLK. All data is driven out of the AD9714/
AD9715/AD9716/AD9717 on the falling edge of SCLK.
CSChip Select
An active low input starts and gates a communications cycle.
It allows more than one device to be used on the same serial
communications lines. The SDIO/FORMAT pin reaches a
high impedance state when this input is high. Chip select
should stay low during the entire communications cycle.
SDIOSerial Data I/O
The SDIO pin is used as a bidirectional data line to transmit
and receive data.

MSB/LSB TRANSFERS
The serial port of the AD9714/AD9715/AD9716/AD9717 can
support both most significant bit (MSB) first or least significant
bit (LSB) first data formats. This functionality is controlled by
the LSBFIRST bit (Register 0x00, Bit 6). The default is MSB first
(LSBFIRST = 0).
When LSBFIRST = 0 (MSB first), the instruction and data bytes
must be written from the most significant bit to the least significant
bit. Multibyte data transfers in MSB first format start with an
instruction byte that includes the register address of the most
significant data byte. Subsequent data bytes should follow in
order from a high address to a low address. In MSB first mode,
the serial port internal byte address generator decrements for
each data byte of the multibyte communications cycle.
When LSBFIRST = 1 (LSB first), the instruction and data bytes
must be written from the least significant bit to the most signifi-
cant bit. Multibyte data transfers in LSB first format start with
an instruction byte that includes the register address of the least
significant data byte followed by multiple data bytes. The serial
port internal byte address generator increments for each byte
of the multibyte communication cycle.
The serial port controller data address of the AD9714/AD9715/
AD9716/AD9717 decrements from the data address written
toward 0x00 for multibyte I/O operations if the MSB first mode
is active. The serial port controller address increments from the
data address written toward 0x1F for multibyte I/O operations
if the LSB first mode is active.
SERIAL PORT OPERATION
The serial port configuration of the AD9714/AD9715/AD9716/
AD9717 is controlled by Register 0x00. It is important to note
that the configuration changes immediately upon writing to the
last bit of the register. For multibyte transfers, writing to this
register can occur during the middle of the communications
cycle. Care must be taken to compensate for this new configu-
ration for the remaining bytes of the current communications cycle.
The same considerations apply to setting the software reset bit
(Register 0x00, Bit 5). All registers are set to their default values
except Register 0x00, which remains unchanged.
Use of single-byte transfers or initiating a software reset is
recommended when changing serial port configurations to
prevent unexpected device behavior.

PIN MODE
The AD9714/AD9715/AD9716/AD9717 can also be operated
without ever writing to the serial port. With the RESET/PINMD
pin tied high, the SCLK pin becomes CLKMD to provide for
clock mode control (see the Retimer section), the SDIO pin
becomes FORMAT and selects the input data format, and the
CS/PWRDN pin serves to power down the device.
Operation is otherwise exactly as defined by the default register
values in Table 13; therefore, external resistors at FSADJI and
FSADJQ are needed to set the DAC currents, and both DACs
are active. This is also a convenient quick checkout mode.
DAC currents can be externally adjusted in pin mode by sourcing
or sinking currents at the FSADJI/AUXI and FSADJQ/AUXQ
pins as desired with the fixed resistors installed. An op amp
output with appropriate series resistance is one of many possibili-
ties. This has the same effect as changing the resistor value.
Place at least 10 kΩ resistors in series right at the DAC to guard
against accidental short circuits and noise modulation. The
REFIO pin can be adjusted ±25% in a similar manner, if desired.

DIGITAL INTERFACE OPERATION
Digital data for the I and Q DACs is supplied over a single
parallel bus (DB[n:0), where n is 7 for the AD9714, 9 for
the AD9715, 11 for the AD9716, and 13 for the AD9717)
accompanied by a qualifying clock (DCLKIO). The I and Q
data are provided to the chip in an interleaved double data
rate (DDR) format. The maximum guaranteed data rate is
250 MSPS with a 125 MHz clock. The order of data pairing
and the sampling edge selection is user programmable using
the IFIRST and IRISING data control bits, resulting in four
possible timing diagrams. These are shown in Figure 89,
Figure 90, Figure 91, and Figure 92.

DIGITAL DATA LATCHING AND RETIMER BLOCK
The AD9714/AD9715/AD9716/AD9717 have two clock inputs,
DCLKIO and CLKIN. The CLKIN is the analog clock whose
jitter affects DAC performance, and the DCLKIO is a digital
clock from an FPGA that needs to have a fixed relationship with
the input data to ensure that the data is picked
up correctly by the flip-flops on the pads.
Figure 94 is a simplified diagram of the entire data capture
system in the AD9714/AD9715/AD9716/AD9717. The double
data rate input data (DB[n:0), where n is 7 for the AD9714, 9
for the AD9715, 11 for the AD9716, and 13 for the AD9717) is
latched at the pads/pins either on the rising edge or the falling edge
of the DCLKIO-INT clock, as determined by IRISING, Bit 4 of
SPI Address 0x02. Bit 5 of SPI Address 0x02, IFIRST, determines
which channel data is latched first (that is, I or Q). The captured
data is then retimed to the internal clock (CLKIN-INT) in the
retimer block before being sent to the final analog DAC core
(D-FF 4), which controls the current steering output switches. All
delay blocks depicted in Figure 94 are noninverting, and any wires
without an explicit delay block can be assumed to have no delay.
Only one channel is shown in Figure 94 with the data pads
(DB[n:0), where n is 7 for the AD9714, 9 for the AD9715, 11 for
the AD9716, and 13 for the AD9717) serving as double data
rate pads for both channels.
The default PINMD and SPI settings are IE = high (closed)
and OE = low (open). These settings are enabled when RESET/
PINMD (Pin 35) is held high. In this mode, the user has to supply
both DCLKIO and CLKIN. In PINMD, it is also recommended
that the DCLKIO and the CLKIN be in phase for proper func-
tioning of the DAC, which can easily be ensured by tying the
pins together on the PCB. If the user can access the SPI, setting
Bit 2 of SPI Address 0x02, DCI_EN, to logic low causes the
CLKIN to be used as the DCLKIO also.
Setting Bit 1 or Bit 0 of SPI Address 0x02, DCOSGL or DCODBL,
respectively, to logic high allows the user to obtain a DCLKIO
output from the CLKIN input for use in the users PCB system.
It is strongly recommended that DCI_EN = DCOSGL = high or
DCI_EN = DCODBL = high not be used even though the
device may appear to function correctly. Similarly, do not set
DCOSGL and DCODBL to logic high simultaneously.
Retimer
The AD9714/AD9715/AD9716/AD9717 have an internal data
retimer circuit that compares the CLKIN-INT and DCLKIO-INT
clocks and, depending on their phase relationship, selects a
retimer clock (RETIMER-CLK) to safely transfer data from
the DCLKIO used at the chips input interface to the CLKIN
used to clock the analog DAC cores (D-FF 4).
The retimer selects one of the three phases shown in Figure 95.
The retimer is controlled by the CLKMODE SPI bits, as shown
in Table 15.

Figure 95. RETIMER-CLK Phases
Note that, in most cases, more than one retimer phase works
and ,in such cases, the retimer arbitrarily picks one phase that
works. The retimer cannot pick the best or safest phase. If the
user has a working knowledge of the exact phase relationship
between DCLKIO and CLKIN (and thus DCLKIO-INT and
CLKIN-INT because the delay is approximately the same for
both clocks and equal to DELAY1), then the retimer can be
forced to this phase with CLKMODEN = 1, as described in
Table 15 and the following paragraphs.

Bit Name Description
CLKMODEQ[1:0] Q data path retimer clock selected output. Valid after the searching bit goes low.
Searching High indicates that the internal data path retimer is searching for the clock relationship (DAC is not usable until it is low again).
Reacquire Changing this bit from 0 to 1 causes the data path retimer circuit to reacquire the clock relationship.
CLKMODEN 0: uses CLKMODEI/CLKMODEQ values (as computed by the two internal retimers) for I and Q clocking.
1: uses the CLKMODE value set in CLKMODEI[1:0] to override the bits for both I and Q retimers (that is, force the retimer).
CLKMODEI[1:0] I data path retimer clock selected output. Valid after searching goes low.
If CLKMODEN = 1, a value written to this register overrides both the I and Q automatic retimer values.

When RESET is pulsed high and then returns low (the part is in
SPI mode), the retimer runs and automatically selects a suitable
clock phase for the RETIMER-CLK within 128 clock cycles. The
SPI searching bit, Bit 4 of SPI Address 0x14, returns to low,
indicating that the retimer has locked and the part is ready for
use. The reacquire bit, Bit 3 of SPI Address 0x14, can be used to
reinitiate phase detection in the I and Q retimers at any time.
CLKMODEQ[1:0] and CLKMODEI[1:0] of SPI Address 0x14
provide readback for the values picked by the internal phase
detectors in the retimer (see Table 16).
To force the two retimers (I and Q) to pick a particular phase
for the retimer clock (they must both be forced to the same
value), CLKMODEN, Bit 2 of SPI Address 0x14, should be set
high and the required phase value is written into CLKMODEI[1:0]
and CLKMODEQ[1:0]. For example, if the DCLKIO and the
CLKIN are in phase to the first order, the user can safely force the
retimers to pick Phase 2 for the RETIMER-CLK. This forcing
function may be useful for synchronizing multiple devices.
In pin mode, it is expected that the user tie CLKIN and DCLKIO
together. The device has a small amount of programmable
functionality using the unused SPI pins (SCLK, SDIO, and CS).
If the two chip clocks are tied together, the SCLK pin can be
tied to ground, and the chip uses a clock for the retimer that is
180° out of phase with the two input clocks (that is, Phase 2,
which is the safest and best option). The chip has an additional
option in pin mode when the redefined SCLK pin is high. Use
this mode if using pin mode, but CLKIN and DCLKIO are not
tied together (that is, not in phase). Holding SCLK high causes
the internal clock detector to use the phase detector output to
determine which clock to use in the retimer (that is, select a
suitable RETIMER-CLK phase). The action of taking SCLK
high causes the internal phase detector to reexamine the two
clocks and determine the relative phase. Whenever the user
wants to reevaluate the relative phase of the two clocks, the
SCLK pin can be taken low and then high again.
ESTIMATING THE OVERALL DAC PIPELINE DELAY
DAC pipeline latency is affected by the phase of the RETIMER-
CLK that is selected. If latency is critical to the system and must
be constant, the retimer should be forced to a particular phase and
not be allowed to automatically select a phase each time.
Consider the case in which DCLKIO = CLKIN (that is, in
phase), and the RETIMER-CLK is forced to Phase 2. Assume
that IRISING is 1 (that is, I data is latched on the rising edge
and Q data is latched on the falling edge). Then the latency to the
output for the I channel is four clock cycles total; one clock cycle
from the input interface (D-FF 1, not D-FF0, as it latches data
on either edge and does not cause any delay); two clock cycles
from the retimer (D-FF 2 and D-FF 4, but not D-FF 3, because
it is latched on the half clock cycle or 180°); and one clock cycle
going through the analog core (D-FF 5). The latency to the output
for the Q channel from the time the falling edge latches it at the
pads in D-FF 0 is 3.5 clock cycles (no delay due to D-FF0, 1 clock
cycle due to D-FF 1, ½ clock cycle to D-FF 2, 1 clock cycle to D-
FF 4, and 1 clock cycle to D-FF 5). This latency for the AD9714/
AD9715/AD9716/AD9717 is case specific and needs to be calcu-
lated based on the RETIMER-CLK phase that is automatically
selected or manually forced.

REFERENCE OPERATION
The AD9714/AD9715/AD9716/AD9717 contain an internal
1.0 V band gap reference. The internal reference can be disabled
by setting Bit 0 (EXTREF) of the power-down register (Address
0x01) through the SPI interface. To use the internal reference,
decouple the REFIO pin to AVSS with a 0.1 μF capacitor, enable
the internal reference, and clear Bit 0 of the power-down register
(Address 0x01) through the SPI interface. Note that this is the
default configuration. The internal reference voltage is present
at REFIO. If the voltage at REFIO is to be used anywhere else in
the circuit, an external buffer amplifier with an input bias current
of less than 100 nA must be used to avoid loading the reference.
An example of the use of the internal reference is shown in
Figure 96.

An external reference can be used in applications requiring
tighter gain tolerances or lower temperature drift. Also, a
variable external voltage reference can be used to implement a
method for gain control of the DAC output.
Recommendations When Using an External Reference
Apply the external reference to the REFIO pin. The internal
reference can be directly overdriven by the external reference,
or the internal reference can be powered down to save power
consumption
The external 0.1 μF compensation capacitor on REFIO is not
required unless specified by the external voltage reference
manufacturer. The input impedance of REFIO is 10 kΩ when
the internal reference is powered up and 1 MΩ when it is
powered down.
REFERENCE CONTROL AMPLIFIER
The AD9714/AD9715/AD9716/AD9717 contain a control
amplifier that regulates the full-scale output current, IxOUTFS.
The control amplifier is configured as a V-I converter, as shown
in Figure 96. The output current, IxREF, is determined by the
ratio of the VREFIO and an external resistor, xRSET, as stated in
Equation 4 (see the DAC Transfer Function section). IxREF, is
mirrored to the segmented current sources with the proper scale
factor to set IxOUTFS, as stated in Equation 3.
The control amplifier allows a 2.5:1 adjustment span of IxOUTFS
from 1 mA to 4 mA by setting IxREF between 125 μA and 31.25 μA
(set xRSET between 8 kΩ and 32 kΩ). The wide adjustment span
of IxOUTFS provides several benefits. The first relates directly to
the power dissipation of the AD9714/AD9715/AD9716/AD9717,
which is proportional to IxOUTFS (see the DAC Transfer Function
section). The second benefit relates to the ability to adjust the
output over a 8 dB range with 0.25 dB steps, which is useful for
controlling the transmitted power. The small signal bandwidth
of the reference control amplifier is approximately 500 kHz.
This allows the device to be used for low frequency, small signal
multiplying applications.
When an external resistor greater than 16 is used on the
FSADJx pins, care must be taken to maintain the high frequency
equivalent circuit to an impedance lower than 16 kΩ by
splitting the resistor into two resistors in series with a 10 nF
capacitor in parallel with the resistor to AVSS (see Figure 97).

DAC TRANSFER FUNCTION
The AD9714/AD9715/AD9716/AD9717 provide two differen-
tial current outputs, IOUTP/IOUTN and QOUTP/QOUTN.
IOUTP and QOUTP provide a near full-scale current output,
IxOUTFS, when all bits are high (that is, DAC CODE = 2N − 1,
where N = 8, 10, 12, or 14 for the AD9714, AD9715, AD9716,
and AD9717, respectively), while IOUTN and QOUTN, the
complementary outputs, provide no current. The current
outputs appearing at the positive DAC outputs, IOUTP and
QOUTP, and at the negative DAC outputs, IOUTN and QOUTN,
are a function of both the input code and IxOUTFS and can be
expressed as follows:
IOUTP = (IDAC CODE/2N) × IIOUTFS (1)
QOUTP = (QDAC CODE/2N) × IQOUTFS
IOUTN = ((2N − 1) − IDAC CODE)/2N × IIOUTFS (2)
QOUTN = ((2N − 1) − QDAC CODE)/2N × IQOUTFS
where:
IDAC CODE and QDAC CODE = 0 to 2N1 (that is, decimal
representation).
IIOUTFS and IQOUTFS are functions of the reference currents, IIREF
and IQREF, respectively, which are nominally set by a reference
voltage, VREFIO, and external resistors, IRSET and QRSET, respec-
tively. IIOUTFS and IQOUTFS can be expressed as follows:
IIOUTFS = 32 × IIREF (3)
IQOUTFS = 32 × IQREF
where:
IIREF = VREFIO/IRSET (4)
IQREF = VREFIO/QRSET
or
IIOUTFS = 32 × VREFIO/IRSET (5)
IQOUTFS = 32 × VREFIO/QRSET
A differential pair (IOUTP/IOUTN or QOUTP/QOUTN)
typically drives a resistive load directly or via a transformer. If
dc coupling is required, the differential pair (IOUTP/IOUTN or
QOUTP/QOUTN) should be connected to matching resistive
loads, xRLOAD, that are tied to analog common, AVSS. The
single-ended voltage output appearing at the positive and
negative nodes is
VIOUTP = IOUTP × IRLOAD (6)
VQOUTP = QOUTP × QRLOAD
VIOUTN = IOUTN × IRLOAD (7)
VQOUTN = QOUTN × QRLOAD
To achieve the maximum output compliance of 1 V at the
nominal 4 mA output current, IRLOAD = QRLOAD must be set
to 250 Ω.
Substituting the values of IOUTP, IOUTN, and IxREF, VIDIFF can
be expressed as
VIDIFF = {(2 × IDAC CODE(2N 1))/2N} × (8)
(32 × VREFIO/IRSET) × IRLOAD
Equation 8 highlights some of the advantages of operating the
AD9714/AD9715/AD9716/AD9717 differentially. First, the
differential operation helps cancel common-mode error sources
associated with IOUTP and IOUTN, such as noise, distortion,
and dc offsets. Second, the differential code-dependent current and
subsequent voltage, VIDIFF, is twice the value of the single-ended
voltage output (that is, VIOUTP or VIOUTN), thus providing twice
the signal power to the load. Note that the gain drift temperature
performance for a single-ended output (VIOUTP and VIOUTN) or
differential output (VIDIFF) of the AD9714/AD9715/AD9716/
AD9717 can be enhanced by selecting temperature-tracking
resistors for xRLOAD and xRSET because of their ratiometric
relationship, as shown in Equation 8.
ANALOG OUTPUT
The complementary current outputs in each DAC, IOUTP/
IOUTN and QOUTP/QOUTN, can be configured for single-
ended or differential operation. IOUTP/IOUTN and QOUTP/
QOUTN can be converted into complementary single-ended
voltage outputs, VIOUTP and VIOUTN, as well as VQOUTP and VQOUTN
via a load resistor, xRLOAD, as described in the DAC Transfer
Function section by Equation 6 through Equation 8. The differen-
tial voltages, VIDIFF and VQDIFF, existing between VIOUTP and VIOUTN,
and VQOUTP and VQOUTN, can also be converted to a single-ended
voltage via a transformer or a differential amplifier configuration.
The ac performance of the AD9714/AD9715/AD9716/AD9717
is optimum and is specified using a differential transformer-
coupled output in which the voltage swing at IOUTP and IOUTN
is limited to ±0.5 V. The distortion and noise performance of
the AD9714/AD9715/AD9716/AD9717 can be enhanced when
it is configured for differential operation. The common-mode
error sources of both IOUTP/IOUTN and QOUTP/QOUTN
can be significantly reduced by the common-mode rejection
of a transformer or differential amplifier. These common-mode
error sources include even-order distortion products and noise.
The enhancement in distortion performance becomes more
significant as the frequency content of the reconstructed wave-
form increases and/or its amplitude increases. This is due to
the first-order cancellation of various dynamic common-mode
distortion mechanisms, digital feedthrough, and noise. Performing
a differential-to-single-ended conversion via a transformer also
provides the ability to deliver twice the reconstructed signal
power to the load (assuming no source termination). Because
the output currents of IOUTP/IOUTN and QOUTP/QOUTN
are complementary, they become additive when processed
differentially.

SELF-CALIBRATION
The AD9714/AD9715/AD9716/AD9717 have a self-calibration
feature that improves the DNL of the device. Performing a self-
calibration on the device improves device performance in low
frequency applications. The device performance in applications
where the analog output frequencies are above 5 MHz are generally
influenced more by dynamic device behavior than by DNL and,
in these cases, self-calibration is unlikely to provide much benefit.
The calibration clock frequency is equal to the DAC clock
divided by the division factor chosen by the DIVSEL value. Each
calibration clock cycle is between 32 and 2048 DAC input clock
cycles, depending on the value of DIVSEL[2:0] (Register 0x0E,
Bits[2:0]). The frequency of the calibration clock should be
between 0.5 MHz and 4 MHz for reliable calibrations. Best
results are obtained by setting DIVSEL[2:0] (Register 0x0E,
Bits[2:0]) to produce a calibration clock frequency between
these values. Separate self-calibration hardware is included
for each DAC. The DACs can be self-calibrated individually or
simultaneously.
To perform a device self-calibration, the following procedure
can be used:
1. Write 0x00 to Register 0x12. This ensures that the
UNCALI and UNCALQ bits are reset.
2. Set up a calibration clock between 0.5 MHz and 4 MHz
using DIVSEL[2:0], and then enable the calibration clock
by setting the CALCLK bit (Register 0x0E, Bit 3).
3. Select the DAC(s) to self-calibrate by setting either Bit 4
(CALSELI) for the I DAC and/or Bit 5 (CALSELQ) for the
Q DAC in Register 0x0E. Note that each DAC contains
independent calibration hardware so that they can be
calibrated simultaneously.
4. Start self-calibration by setting the CALEN bit (Register 0x12,
Bit 4). Wait approximately 300 calibration clock cycles.
5. Check if the self-calibration has completed by reading
the CALSTATI bit (Bit 6) and CALSTATQ bit (Bit 7) in
Register 0x0F. Logic 1 indicates that the calibration has
completed.
6. When the self-calibration has completed, write 0x00 to
Register 0x12.
7. Disable the calibration clock by clearing the CALCLK bit
(Register 0x0E, Bit 3).
The AD9714/AD9715/AD9716/AD9717 allow reading and
writing of the calibration coefficients. There are 32 coefficients
in total. The read/write feature of the coefficients can be useful
for improving the results of the self-calibration routine by
averaging the results of several self-calibration cycles and
loading the averaged results back into the device.
To read the calibration coefficients, use the following steps:
1. Select which DAC core to read by setting either Bit 4
(CALSELI) for the I DAC or Bit 5 (CALSELQ) for the
Q DAC in Register 0x0E. Write the address of the first
coefficient (0x01) to Register 0x10.
2. Set the SMEMRD bit (Register 0x12, Bit 2) by writing 0x04
to Register 0x12.
3. Read the 6-bit value of the first coefficient by reading the
contents of Register 0x11.
4. Clear the SMEMRD bit by writing 0x00 to Register 0x12.
5. Repeat Step 2 through Step 4 for each of the remaining 31
coefficients by incrementing the address by 1 for each read.
6. Deselect the DAC core by clearing either Bit 4 (CALSELI)
for the I DAC or Bit 5 (CALSELQ) for the Q DAC in
Register 0x0E.
To write the calibration coefficients to the device, use the
following steps:
1. Select which DAC core to write to by setting either Bit 4
(CALSELI) for the I DAC or Bit 5 (CALSELQ) for the Q
DAC in Register 0x0E.
2. Set the SMEMWR bit (Register 0x12, Bit 3) by writing 0x08
to Register 0x12.
3. Write the address of the first coefficient (0x01) to
Register 0x10.
4. Write the value of the first coefficient to Register 0x11.
5. Repeat Step 2 through Step 4 for each of the remaining 31
coefficients by incrementing the address by one for each
write.
6. Clear the SMEMWR bit by writing 0x00 to Register 0x12.
7. Deselect the DAC core by clearing either Bit 4 (CALSELI)
for the I DAC or Bit 5 (CALSELQ) for the Q DAC in
Register 0x0E.

COARSE GAIN ADJUSTMENT
Option 1
A coarse full-scale output current adjustment can be achieved
using the lower six bits in Register 0x0D. This adds or subtracts
up to 20% from the band gap voltage on Pin 34 (REFIO), and
the voltage on the FSADJx resistors tracks this change. As a
result, the DAC full-scale current varies by the same amount.
A secondary effect to changing the REFIO voltage is that the
full-scale voltage in the AUXDAC also changes by the same
magnitude. The register uses twos complement format, in
which 011111 maximizes the voltage on the REFIO node
and 100000 minimizes the voltage.

Option 2
While using the internal FSADJx resistors, each main DAC can
achieve independently controlled coarse gain using the lower
six bits of Register 0x04 (IRSET[5:0]) and Register 0x07
(QRSET[5:0]). Unlike Coarse Gain Option 1, this impacts only
the main DAC full-scale output current. The register uses twos
complement format and allows the output current to be changed
in approximately 0.25 dB steps.

Option 3
Even when the device is in pin mode, full-scale values can be
adjusted by sourcing or sinking current from the FSADJx pins.
Any noise injected here appears as amplitude modulation of the
output. Thus, a portion of the required series resistance (at least
20 kΩ) must be installed right at the pin. A range of ±10% is
quite practical using this method.
Option 4
As in Option 3, when the device is in pin mode, both full-scale
values can be adjusted by sourcing or sinking current from the
REFIO pin. Noise injected here appears as amplitude modulation
of the output; therefore, a portion of the required series resis-
tance (at least 10 kΩ) must be installed at the pin. A range of
±25% is quite practical when using this method.
Fine Gain
Each main DAC has independent fine gain control using the
lower six bits in Register 0x03 (I DAC gain) and Register 0x06
(Q DAC gain). Unlike Coarse Gain Option 1, this impacts only
the main DAC full-scale output current. These registers use straight
binary format. One application in which straight binary format
is critical is for side-band suppression while using a quadrature
modulator. This is described in more detail in the Applications
Information section.

USING THE INTERNAL TERMINATION RESISTORS
The AD9717/AD9716/AD9715/AD9714 have four 500 Ω
termination internal resistors (two for each DAC output).
To use these resistors to convert the DAC output current to a
voltage, connect each DAC output pin to the adjacent load pin.
For example, on the I DAC, IOUTP must be shorted to RLIP
and IOUTN must be shorted to RLIN. In addition, the CMLI
or CMLQ pin must be connected to ground directly or through
a resistor. If the output current is at the nominal 2 mA and the
CMLI or CMLQ pin is tied directly to ground, this produces a
dc common-mode bias voltage on the DAC output equal to 0.5 V.
If the DAC dc bias must be higher than 0.5 V, an external
resistor can be connected between the CMLI or CMLQ pin and
ground. This part also has an internal common-mode resistor
that can be enabled. This is explained in the Using the Internal
Common-Mode Resistor section.

outputs. By default, the common-mode resistor is not con-
nected. When enabled, it can be adjusted from ~250 Ω to
~1 kΩ. Each main DAC has an independent adjustment
using the lower six bits in Register 0x05 (IRCML[5:0]) and
Register 0x08 (QRCML[5:0]).

Using the CMLx Pins for Optimal Performance
The CMLx pins also serve to change the DAC bias voltages
in the parts allowing them to run at higher dc output bias
voltages. When running the bias voltage below 0.9 V and an
AVDD of 3.3 V, the parts perform optimally when the CMLx
pins are tied to ground. When the dc bias increases above 0.9 V,
set the CMLx pins at 0.5 V for optimal performance. The maxi-
mum dc bias on the DAC output should be kept at or below 1.2 V
when the supply is 3.3 V. When the supply is 1.8 V, keep the dc
bias close to 0 V and connect the CMLx pins directly to ground.

APPLICATIONS INFORMATION
OUTPUT CONFIGURATIONS
The following sections illustrate some typical output confi-
gurations for the AD9714/AD9715/AD9716/AD9717. Unless
otherwise noted, it is assumed that IxOUTFS is set to a nominal
2 mA. For applications requiring the optimum dynamic perfor-
mance, a differential output configuration is suggested. A
differential output configuration can consist of either an
RF transformer or a differential op amp configuration. The
transformer configuration provides the optimum high fre-
quency performance and is recommended for any application
that allows ac coupling. The differential op amp configuration
is suitable for applications requiring dc coupling, signal gain,
and/or a low output impedance.
A single-ended output is suitable for applications in which low
cost and low power consumption are primary concerns.
DIFFERENTIAL COUPLING USING A TRANSFORMER
An RF transformer can be used to perform a differential-to-
single-ended signal conversion, as shown in Figure 103. The
distortion performance of a transformer typically exceeds
that available from standard op amps, particularly at higher
frequencies. Transformer coupling provides excellent rejection
of common-mode distortion (that is, even-order harmonics)
over a wide frequency range. It also provides electrical isolation
and can deliver voltage gain without adding noise. Transformers
with different impedance ratios can also be used for impedance
matching purposes. The main disadvantages of transformer
coupling are low frequency roll-off, lack-of-power gain, and
high output impedance.

Figure 103. Differential Output Using a Transformer
The center tap on the primary side of the transformer must be
connected to a voltage that keeps the voltages on IOUTP and
IOUTN within the output common-mode voltage range of the
device. Note that the dc component of the DAC output current
is equal to IxOUTFS and flows out of both IOUTP and IOUTN.
The center tap of the transformer should provide a path for
this dc current. In most applications, AGND provides the most
convenient voltage for the transformer center tap. The complemen-
tary voltages appearing at IOUTP and IOUTN (that is, VIOUTP
and VIOUTN) swing symmetrically around AGND and should be
maintained with the specified output compliance range of the
AD9714/AD9715/AD9716/AD9717.
A differential resistor, RDIFF, can be inserted in applications
where the output of the transformer is connected to the load,
RLOAD, via a passive reconstruction filter or cable. RDIFF, as
reflected by the transformer, is chosen to provide a source
termination that results in a low voltage standing wave ratio
(VSWR). Note that approximately half the signal power is
dissipated across RDIFF.
SINGLE-ENDED BUFFERED OUTPUT USING
AN OP AMP
An op amp such as the ADA4899-1 can be used to perform
a single-ended current-to-voltage conversion, as shown in
Figure 104. The AD9714/AD9715/AD9716/AD9717 are config-
ured with a pair of series resistors, RS, off each output. For best
distortion performance, RS should be set to 0 Ω. The feedback
resistor, RFB, determines the peak-to-peak signal swing by the
formula
VOUT = RFB × IFS

A dual op amp (see the circuit shown in Figure 105) can be used
in a differential version of the single-ended buffer shown in
Figure 104. The same RC network is used to form a one-pole
differential, low-pass filter to isolate the op amp inputs from

AUXILIARY DACs
The DACs of the AD9714/AD9715/AD9716/AD9717 feature
two versatile and independent 10-bit auxiliary DACs suitable
for dc offset correction and similar tasks.
Because the AUXDACs are driven through the SPI port, they
should never be used in timing-critical applications, such
as inside analog feedback loops.
To keep the pin count reasonable, these auxiliary DACs each
share a pin with the corresponding FSADJx resistor. They are,
therefore, usable only when enabled and when that DAC is
operated on its internal full-scale resistors. A simple I-to-V
converter is implemented on chip with selectable shunt resistors
(3.2 kΩ to 16 kΩ) such that if REFIO is set to exactly 1 V, REFIO/2
equals 0.5 V and the following equation describes the no load
output voltage:

Two registers are assigned to each DAC with 10 bits for the actual
DAC current to be generated, a 3-bit offset (and gain) adjust-
ment, a 2-bit current range adjustment, and an enable/disable
bit. Setting the QAUXOFS (Register 0x0A, Bits[4:2]) and
IAUXOFS (Register 0x0C, Bits[4:2]) bits to all 1s disables the
respective op amp and routes the DAC current directly to the
respective FSADJI/AUXI or FSADJQ/AUXQ pins. This is
especially useful when the loads to be driven are beyond the
limited capability of the on-chip amplifier.
When not enabled (QAUXEN or IAUXEN = 0), the respective
DAC output is in open circuit.
DAC-TO-MODULATOR INTERFACING
The auxiliary DACs can be used for local oscillator (LO) cancella-
tion when the DAC output is followed by a quadrature modulator.
This LO feedthrough is caused by the input referred dc offset
voltage of the quadrature modulator (and the DAC output offset
voltage mismatch) and can degrade system performance. Typical
DAC-to-quadrature modulator interfaces are shown in Figure 108
and Figure 109, with the series resistor value chosen to give an
appropriate adjustment range. Figure 108 also shows external
load resistors in use. Often, the input common-mode voltage for
the modulator is much higher than the output compliance range
of the DAC, so that ac coupling or a dc level shift is necessary. If
the required common-mode input voltage on the quadrature
modulator matches that of the DAC, the dc blocking capacitors in
Figure 108 can be removed and the on-chip resistors can be
connected.

Figure 108. Typical Use of Auxiliary DACs and External Components for
Coupling to Quadrature Modulators
Figure 109 shows a greatly simplified circuit that takes full
advantage of the internal components supplied in the DAC. A
low-pass or band-pass passive filter is recommended when
spurious signals from the DAC (distortion and DAC images)
at the quadrature modulator inputs can affect the system
performance. In the example shown in Figure 109, the filter
must be able to pass dc to properly bias the modulator. Placing
the filter at the location shown in Figure 108 and Figure 109
allows easy design of the filter because the source and load imped-
ances can easily be designed close to 500 Ω for a 2 mA full-scale
output. Once the resistance at the modulator inputs is known,
the user can easily look up the range of input offsets that may be
encountered and compute a value for the series resistor on the
AUXDAC output.

CORRECTING FOR NONIDEAL PERFORMANCE OF
QUADRATURE MODULATORS ON THE IF-TO-RF
CONVERSION
Analog quadrature modulators make it very easy to realize
single sideband radios. However, there are several nonideal
aspects of quadrature modulator performance. Among these
analog degradations are gain mismatch and LO feedthrough.
Gain Mismatch
The gain in the real and imaginary signal paths of the quad-
rature modulator may not be matched perfectly. This leads
to less than optimal image rejection because the cancellation of
the negative frequency image is less than perfect.
LO Feedthrough
The quadrature modulator has a finite dc referred offset, as well
as coupling from its LO port to the signal inputs. These can lead
to a significant spectral spur at the frequency of the quadrature
modulator LO.
The AD9714/AD9715/AD9716/AD9717 have the capability
to correct for both of these analog degradations. However,
understand that these degradations drift over temperature;
therefore, if close to optimal single sideband performance
is desired, a scheme for sensing these degradations over
temperature and correcting them may be necessary.
I/Q-CHANNEL GAIN MATCHING
Fine gain matching is achieved by adjusting the values in the
DAC fine gain adjustment registers. For the I DAC, these values
are in the I DAC gain register (Register 0x03). For the Q DAC,
these values are in the Q DAC gain register (Register 0x06). These
are 6-bit values that cover ±2% of full scale. To perform gain
compensation starting from the default values of zero, raise the
value of one of these registers a few steps until it can be deter-
mined if the amplitude of the unwanted image is increased or
decreased. If the unwanted image increases in amplitude, remove
the step and try the same adjustment on the other DAC control
register. Iterate register changes until the rejection cannot be
improved further. If the fine gain adjustment range is not sufficient
to find a null (that is, the register goes full scale with no null
apparent), adjust the course gain settings of the two DACs
accordingly and try again. Variations on this simple method
are possible.
Data Sheet AD9714/AD9715/AD9716/AD9717
Rev. B | Page 51 of 80
Note that LO feedthrough compensation is independent of
phase compensation. However, gain compensation can affect
the LO compensation because the gain compensation may
change the common-mode level of the signal. The dc offset of
some modulators is common-mode level dependent. Therefore,
it is recommended that the gain adjustment be performed prior
to LO compensation.
LO FEEDTHROUGH COMPENSATION
To achieve LO feedthrough compensation in a circuit, each
output of the two AUXDACs must be connected through a
100 kΩ resistor to one side of the differential DAC output. See
the Auxiliary DACS section for details of how to use AUXDACs.
The purpose of these connections is to drive a very small amount
of current into the nodes at the quadrature modulator inputs,
thereby adding a slight dc bias to one or the other of the
quadrature modulator signal inputs.
To achieve LO feedthrough compensation, the user should start
with the default conditions of the AUXDAC registers, and then
increment the magnitude of one or the other AUXDAC output
voltages. While this is being done, the amplitude of the LO
feedthrough at the quadrature modulator output should be
sensed. If the LO feedthrough amplitude increases, try either
decreasing the output voltage of the AUXDAC being adjusted,
or try adjusting the output voltage of the other AUXDAC. It
may take practice before an effective algorithm is achieved. The
AD9714/AD9715/AD9716/AD9717 evaluation board can be
used to adjust the LO feedthrough down to the noise floor,
although this is not stable over temperature.
RESULTS OF GAIN AND OFFSET CORRECTION
The results of gain and offset correction can be seen in Figure 110
and Figure 111. Figure 110 shows the output spectrum of the
quadrature demodulator before gain and offset correction.
Figure 111 shows the output spectrum after correction. The
LO feedthrough spur at 450 MHz has been suppressed to the
noise level. This result can be achieved by applying the correc-
tion, but the correction must be repeated after a large change in
temperature.
Note that gain matching improves the negative frequency image
rejection, but it is also related to the phase mismatch in the
quadrature modulator. It can be improved by adjusting the
relative phase between the two quadrature signals at the digital
side or properly designing the low-pass filter between the DACs
and quadrature modulators. Phase mismatch is frequency depen-
dent; therefore, routines must be developed to adjust it if
wideband signals are desired.

MODIFYING THE EVALUATION BOARD TO
USE THE ADL5370 ON-BOARD QUADRATURE
MODULATOR
The evaluation board contains an Analog Devices, Inc.,
ADL5370 quadrature modulator. The AD9714/AD9715/
AD9716/AD9717 and the ADL5370 provide an easy-to-
interface DAC/modulator combination that can be easily
characterized on the evaluation board. Solderable jumpers
can be configured to evaluate the single-ended or differential
outputs of the AD9714/AD9715/AD9716/AD9717. This setup
is the default configuration from the factory and consists of
the following population of the components:
JP55, JP56, JP76, JP82unsoldered
R13, R14, R52, R53unpopulated
R50, R57, T1, T2populated
To evaluate the ADL5370 on this board, the population of these
same components should be reversed so that they are in the
following positions:
JP55, JP56, JP76, JP82soldered
R13, R14, R52, R53populated
R50, R57, T1, T2unpopulated
The AUXDAC outputs can be connected to Test Point TP44 and
Test Point TP45 if LO feedthrough compensation is necessary.
