The DAC5670 is clocked at the DAC sample rate and the two input ports run at a maximum of 1.2 GSPS. An additional reference bit input sequence is used to adjust the output clock delay to the data source, optimizing the internal data latching clock relative to this reference bit with a delay lock loop (DLL). Alternatively, the DLL may be bypassed and the timing interface managed by controlling DATA setup and hold timing to DLYCLK. The DAC5670 also can accept data up to 1.2 GSPS on one input port the same clock configuration. In the single port mode, repeating the input sample (A_ONLY mode), 2 times interpolation by zero stuff (A_ONLY_ZS mode), or 2 times interpolation by repeating and inverting the input sample (A_ONLY_INV) are used to double the input sample rate up to 2.4 GSPS. The DAC5670 operates with a single 3-V to 3.6-V supply voltage. Power dissipation is 2 W at maximum operating conditions. The DAC5670 provides a nominal full-scale differential current-output of 20 mA, supporting both single-ended and differential applications. An on-chip 1.2-V temperature-compensated bandgap reference and control amplifier allows the user to adjust the full-scale output current from the nominal 20 mA to as low as 5 mA or as high as 30 mA. The output current can be directly fed to the load with no additional external output buffer required. The device has been specifically designed for a differential transformer coupled output with a 50- doubly-terminated load. The DAC5670 is available in a 192-ball CBGA package. The device is characterized for operation over the military temperature range ( -55C to 125C Tcase). 1 2 Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

The DAC5670 consists of a segmented array of NPN-transistor current sinks, capable of delivering a full-scale output current up to 30mA. Differential current switches direct the current of each current sink to either one of the complementary output nodes IOUT_P or IOUT_N. The complementary current output enables differential operation, canceling out common-mode noise sources (digital feed-through, on-chip and PCB noise), dc offsets, and even-order distortion components, and doubling signal output power. The full-scale output current is set using an external resistor (RBIAS) in combination with an on-chip bandgap voltage reference source (1.2V) and control amplifier. The current (IBIAS) through resistor RBIAS is mirrored internally to provide a full-scale output current equal to 32 times IBIAS. The full-scale current is adjustable from 30mA down to 5mA by using the appropriate bias resistor value. Figure 10.

Figure 11. Digital Input Voltage Options The DAC5670 uses low voltage differential signaling (LVDS and Hyper-Transport) for the bus input interface. The LVDS and Hyper-Transport input modes feature a low differential voltage swing. The differential characteristic of LVDS and Hyper-Transport modes allow for high-speed data transmission with low electromagnetic interference (EMI) levels. Figure 12 shows the equivalent complementary digital input interface for the DAC5670, valid for pins DA_P[13:0], DA_N[13:0], DB_P[13:0], and DB_N[13:0].

Figure 13. DLL Usage The DAC5670 is clocked at the DAC sample rate. Each input port runs at a maximum of 1.2 GSPS. The DAC5670 provides an output clock (DLYCLK) at one-half the input port data rate (DACCLK/4), and monitors an additional reference bit (DTCLK). DTCLK is used as feedback clock to adjust interface timing. To accomplish this, the DAC5670 implements a delay locked loop (DLL) to help manage the timing interface from external data source. As with all DLLs, there are limitations on the capability of the DLL with respect to the delay chain length, implementation of the phase detector, and the bandwidth of the control loop. The DAC5670 implements a quadrature based phase detector. This scheme allows for the DLL to provide maximum setup/hold delay margins when quadrature can be reached. Quadrature is reached when the internal CLK/4 is 90 out of phase with DTCLK. Additionally, as the frequency of operation decreases, the delay line's fixed length limits its ability to change the delay path enough to reach quadrature. See Figure 15. It is also worth noting that the delay line has asymetric attriubes. The NegD range is smaller than the PosD range. From its nominal (restart) position, it can delay more than it can subtract. Figure 15 represents the behavior of the phase detector and the delay line with respect to initial positions of the rising edge of DTCLK. There are 4 distinct quadrants that define the behavior. Each quadrant represents the period of the DDR clock rate (600 Mhz in the 2.4 GSPS case) divided by 4. The ideal location has the initial delays of DTCLK (and hence data bits) in quadrant 1. The stable lock point of DLL is at T/4, between Q1 and Q2. If DTCLK's initial delay is in quadrants 3 or 4, the INV_CLK pin can be asserted to improve ability of DLL to obtain quadrature. This will move the stable quadrature point to the center of 3T/4 vs T/4 as shown in Figure 15. Essentially the zones that add delay become zones that subtract delay and vice-versa. The clock phase of CLK/4 would also invert. In cases where it is not appropriate to use the DLL to manage the timing interface, it is possible to utilize fixed setup and hold values for DA and DB signals relative to the generated DLYCLK output when the DLL is held in restart. This is accomplished by asserting RESTART to logic high and using the timing input conditions for external timing interface with DLL in restart in the recommended operating conditions table. DTCLK does not need to be provided when using external setup and hold timing. DTCLK should be biased to valid LVDS levels in that case. See Figure 17.

The current flow through IOUT_P and IOUT_N is controlled by Dx_P[13:0] and Dx_N[13:0]. For ease of use, we denote D[13:0] as the logical bit equivalent of Dx_P[13:0] and its complement Dx_N[13:0]. The DAC5670 supports straight binary coding with D13 being the MSB and D0 the LSB. Full-scale current flows through IOUTP when all D[13:0] inputs are set high and through IOUTN when all D[13:0] inputs are set low. The relationship between IOUT_P and IOUT_N can be expressed as Equation 1: IOUT_N = IO(FS) - IOUT_P (1) (1) IO(FS) is the full-scale output current sink (5 mA to 30 mA). Since the output stage is a current sink, the current can only flow from AVDD through the load resistors RL into the IOUT_N and IOUT_P pins. The output current flow in each pin driving a resistive load can be expressed as shown in Figure 23, as well as in Equation 2 and Equation 3. Figure 23. Relationship between D[13:0], IOUT_N and IOUT_P IOUT_N = (IOUT(FS) x (16383 - CODE)) / 16384 (2) IOUT_P = (IOUT(FS) x CODE) / 16384 (2) (3) (3) where CODE is the decimal representation of the DAC input word. This would translate into single-ended voltages at IOUT_N and IOUT_P, as shown in Equation 4 and Equation 5: VOUTN = AVDD - IOUT_N x RL (4) (4) VOUTP = AVDD - IOUT_P x RL (5) (5) For example, assuming that D[13:0] = 1 and that RL is 50 , the differential voltage between pins IOUT_N and IOUT_P can be expressed as shown in Equation 6 through Equation 8 where IO(FS) = 20 mA: VOUTN = 3.3 V - 0 mA x 50 = 3.3 V (6) (6) VOUTP = 3.3 V - 20 mA x 50 = 2.3 V (7) (7) VDIFF = VOUTN - VOUTP = 1 V (8) (8) If D[13:0] = 0, then IOUT_P = 0 mA and IOUT_N = 20 mA and the differential voltage VDIFF = -1 V. The output currents and voltages in IOUT_N and IOUT_P are complementary. The voltage, when measured differentially, will be doubled compared to measuring each output individually. Care must be taken not to exceed the compliance voltages at the IOUT_N and IOUT_P pins in order to keep signal distortion low.

Reference Circuit The DAC5670 comprises a bandgap reference and control amplifier for biasing the full-scale output current. The full-scale output current is set by applying an external resistor RBIAS to pins RBIASOUT and RBIASIN. The bias current IBIAS through resistor RBIAS is defined by the on-chip bandgap reference voltage and control amplifier. The full-scale output current equals 32 times this bias current. The full-scale output current IOUTFS can thus be expressed as: IOUTFS = 32 x IBIAS = 32 x VREFIO/RBIAS (9) (9) Where: VREFIO Voltage at terminals REFIO and REFIO_IN The bandgap reference voltage delivers an accurate voltage of 1.2 V. An external REFIO filter capacitor of 0.1 F should be connected externally to the terminals REFIO and REFIO_IN for compensation.

Differential NPN switches direct the current of each individual NPN current sink to either the positive output node IOUT_P or its complementary negative output node IOUT_N.

The DAC5670 can easily be configured to drive a doubly-terminated 50 cable using a properly selected transformer. Figure 26 and Figure 27 show the 1:1 and 4:1 impedance ratio configuration, respectively. These configurations provide maximum rejection of common-mode noise sources and even-order distortion components, thereby doubling the power of the DAC to the output. The center tap on the primary side of the transformer is terminated to AVDD, enabling a dc current flow for both IOUT_N and IOUT_P.
