2 Electrica l Characteristics
This document contains detailed information on power considerations, DC/AC electrical characteristics, and AC timing
specifications. For additional information, see the MSC8144EC Reference Manual.
2.1 Maximum Ratings
In calculat ing timi ng requir ements, adding a maximu m value o f one specification to a minimu m value of anoth er specification
does not yield a reasonable sum. A maximum specification is calculated using a worst case variation of process parameter values
in one direction. The minimum specification is calculated using the worst case for the same parameters in the opposite direction.
Therefore, a “maximum” value for a specification never occurs in the same device with a “minimum” value for another
specification; adding a maximum to a minimum represents a condition that can never exist.
Table 2 describes the maximum electrical ratings for the MSC8144EC.
CAUTION
This device contains circuitry protecting against damage
due to high static voltage or electrical fields; however,
normal precautions should be taken to avoid exceeding
maximum voltage ratings. Reliability is enhanced if unused
inputs are tied to an appropriate logic voltage level (for
example, either GND or VDD).

2.5.2 Serial RapidIO DC Electrical Cha racteristics
DC receiver logic levels are not defined since the receiver is AC-coupled.
2.5.2.1 DC Requirements for SerDes Reference Clocks
The SerDes reference clocks SRIO_REF_CLK and SRIO_REF_CLK are AC-coupled differential inputs. Each differential
clock input has an intern al 50 Ω termin ation to GNDSXC. The reference clock must be able to drive this ter m ination. The
recommended minimum operating voltage is –0.4 V; the recommended maximum operating voltage is 1.32 V; and the
maximum absolute voltag e is 1.72 V.
The maximum average current allowed in each input is 8 mA. This current limitation sets the maximum common mode input
voltage to be less than 0.4 V (0.4 V/50 Ω = 8 mA) while the minimum commo n mo de in put lev e l is GNDSXC. For example, a
clock with a 50 /50 duty cycle can be driven by a current s ource ou tput that ranges from 0 mA to 16 mA (0–0.8 V). The input is
AC-coupled internally, so, therefore, the exact common mode input voltage is not critical.
Note: This internal AC-couple network does not function correctly with reference clock frequencies below 90 MHz.
If the device driving the SRIO_REF_CLK inputs cannot drive 50 Ω to GNDSXC, or if it exceeds the maximum input current
limitations, then it must use external AC-coupling. The minimum differential peak-to-peak amplitude of the input clock is 0.4 V
(0.2 V peak-to-peak per phase). T he maximum differential peak-to-peak amplitude of the input clock is 1.6 V peak-to-peak (see
Figure 5. The termination to GNDSXC allows compatibility with HCSL type reference clocks specified for PCI-Express
applications. Many other low voltage differential type outputs can be used b ut will probably need to be AC-coupled due to the
limited commo n mode input range. LVPECL outputs can produce too lar ge an amplitude and may need to be source terminated
with a d ivider networ k to r educe the ampl itude. Th e amplitude of the clock mus t be at least a 400 mV d ifferential p eak-peak for
single-ended clock. If driven differentially, each signal wire needs to drive 100 mV around common mode voltage. The
differential reference clock (SRIO_REF_CLK/ SRIO_REF_CLK) input is HCSL-compatible DC coupled or LVDS-compatible
with AC-coupling.

2.5.2.2 Spread Spectrum Clock
SRIO_REF_CLK/ SRIO_REF_CLK is designed to work with a spread spectrum clock (0 to 0.5% spreading at 3033 kHz rate
is allowed), assuming both ends have same reference clock. For better r esults use a source without significant unintended
modulation.

2.6 AC Timings
The following sections include illustrations and tables of clock diagrams, signals, and parallel I/O outputs and inputs.
2.6.1 Start-Up Timing
Starting the device requires coordination among several input sequences including clocking, reset, and power. Section 2.6.2
describes the clocking characteristics. Section 2.6.3 describes the reset and power-up characteristics. You must use the
following guidelines when starting up an MSC8144EC device:
• PORESET and TRST mu st be as sert ed ex ternally f or the d uration of the power-up sequence using the VDDIO (3.3 V)
supply. See Table 19 for timing. TRST must be deasserted before normal operation begins to ensure correct
initialization of the Security Engine .
Note: For applications that use M3 memory, M3_RESET should replicate the PORESET sequence timing, but using the
VDDM3IO (2.5 V) supply. See Section 3.1.1, Power-on Sequence for additional design information.
•CLKIN should start toggling at least 32 cycles before the PORESET deassertion to guarantee co rrect device operatio n
(see Figure 6). 32 cycles should be accounted only after VDDIO reaches its nominal value.
• CLKIN and PCI_CLK_IN shou ld either be stable low during the power -up of VDDIO supply and start their swings after
power-up or should swing within VDDIO range during VDDIO power-up., so their amplitude grows as VDDIO grows
during power-up.
Figure 6 shows a sequence in which VDDIO is raised after VDD and CLKIN begins to toggle with the raise of VDDIO supply.
2.6.2 Clock and Timing Signals
The followin g sections include a des cription of clock signal characteristics. Table 16 shows the maximu m frequency v alues fo r
CLKIN and PCI_CLK_IN. The user must ensure that maximum frequency values are not exceeded.

2.6.3 Reset Timing
The MSC8144EC has several inputs to the reset logic:
• Power-on reset (PORESET)
• E xternal hard reset (HRESET)
• External soft reset (SRESET)
• Software watchdog reset
•JTAG reset
• RapidIO reset
• Software hard reset
• Software soft reset
All MSC8144EC reset so urces are fed into the reset controller, which takes di fferent actions depending on the sour ce of the
reset. The reset status register indicates the most recent sources to cause a reset. Table 17 describes the reset sources.
Table 17. Reset Sources
Table 18 summarizes the reset actions that occur as a result of the different reset sources.
Name Direction Description
Power-on reset
(PORESET)Input Initiates the power-on reset flow that resets the MSC8144EC and configures various attributes of the
MSC8144EC. On PORESET , the entire MSC8144EC device is reset. All PLLs states is reset,
HRESET and SRESET are driven, the extended cores are reset, and system configuration is
sampled. The reset source and word are configured only when PORESET is asserted.
External hard
reset (HRESET)Input/ Output Initiates the hard reset flow that configures various attributes of the MSC8144EC. While HRESET is
asserted, S RES ET is also asserted. HRESET is an open-drain pin. Upon hard reset, HRESET and
SRESET are driven, the extended cores are reset, and system configuration is sampled. Note that
the RCW (reset Configuration Word) is not reloaded during HRESET assertion after out of power on
reset sequence. The reset configuration word is described in the Reset chapter in the MSC8144EC
Reference Manual.
External soft reset
(SRESET)Input/ Output Initiates the soft reset flow. The MSC8144EC detects an external assertion of SRESET only if it
occurs while the MSC8144EC is not asserting reset. SRESET is an open-drain pin. Upon soft reset,
SRESET is driven, the extended cores are reset, and system configuration is maintained.
Host reset
command through
the TAP
Internal When a host reset command is written through the Test Access Port (TAP), the TAP logic asserts the
soft reset signal and an internal soft reset sequence is generated.
Software
watchdog reset Internal When the MSC8144EC watchdog count reaches zero, a software watchdog reset is signalled. The
enabled software watchdog event then generates an internal hard reset sequence.
RapidIO reset Internal When the RapidIO logic asserts the RapidIO hard reset signal, it generates an internal hard reset
sequence.
Software hard
reset Internal A hard reset sequence can be initialized by writing to a memory mapped register (RCR)
Software soft reset Internal A soft reset sequence can be initialized by writing to a memory mapped register (RCR)

2.6.3.1 Power-On Reset (PORESET) Pin
Asserting PORESET initiates the power-on reset flow. PORESET must be asserted externally fo r at least 32 CLKIN cycles after
VDD and VDDIO are both at their nominal levels.
2.6.3.2 Reset Configuration
The MSC8144EC has two mechanisms for writing the reset configuration:
• Through the I2C port
• Through exte rnal pi ns
• Through internal hard coded
Twenty-three signals (s ee Section 1 for signal description details) are sampled during the power-on reset sequence to define the
Reset Word Configuration Source and operating conditions:
• RCW_SRC[2–0]
• RC[16–0]
The RCFG_CLKIN_RNG pin must be valid during power-on or hard reset sequence. The STOP_BS pin must be always valid
and is also sampled during power-on reset sequence for RCW loading from an I2C EEPROM.

Notes: 1. The symbols used for timing specifications follow the pattern of t(first two letters of functional block)(signal)(state) (reference)(state) for
inputs and t(first two letters of functional block)(reference)(state)(signal)(state) for outputs. Output hold time can be read as DDR timing
(DD) from the rising or falling edge of the reference clock (KH or KL) until the output went invalid (AX or DX). For example,
tDDKHAS symbolizes DDR timing (DD) for the time tMCK memory clock reference (K) goes from the high (H) state until outputs
(A) are setup (S) or output valid time. Also, tDDKLDX symbolizes DDR timing (DD) for the time tMCK mem o ry clock reference
(K) goes low (L) until data outputs (D) are invalid (X) or data output hold time.
2. All MCK/MCK referenced measurements are made from the crossing of the two signals ±0.1 V.
3. ADDR/CMD includes all DDR SDRAM output signals except MCK/MCK, MCS, and MDQ/MECC/MDM/MDQS. For the
ADDR/CMD setup and hold specifications, it is assumed that the Clock Control register is set to adjust t he memory clocks by
1/2 applied cycle.
4. Note that tDDKHMH follows the symbol conventions described in note 1. For example, tDDKHMH describes the DDR timing (DD)
from the rising edge of the MCK(n) clock (KH) until the MDQS signal is valid (MH). tDDKHMH can be modified through control
of the DQSS override bits in the TIMING_CFG_2 register. This will typically be set to the same delay as the clock adjust in the
CLK_CNTL register. The timing parameters listed in the table assume that these 2 parameters have been set to the same
adjustment value. See the MSC8144EC Reference Manual for a description and understanding of the timing modifications
enabled by use of these bits.
5. Determined by maximum possible skew between a data strobe (MDQS) and any corresponding bit of data (MDQ), ECC
(MECC), or data mask (MD M). The data strobe should be centered inside of the data eye at the pins of the microprocessor.
6. All outputs are referenced to the rising edge of MCK(n) at the pins of the microprocessor. Note that tDDKHMP follows the
symbol conventions described in note 1.
7. At recommended operating conditions with VDDDDR (1.8 V or 2.5 V) ± 5%.

Table 24 lists AC signal specifications.
2.6.5.2 Signal Definitions
LP-Serial links use differential signalin g. This section defines terms used in the des cri ption and specification of differential
signals. Figure 11 shows how the signals are defined. The figure shows waveforms for either a transmitter output (TD and TD)
or a recei ver in put (RD and RD). Each signal swings between voltage levels A and B, where A > B.
Note: This explanation uses generic TD/TD/RD/RD signal names. These correspond to SRIO_TXD/SRIO_TXD/
SRIO_RXD/SRIO_RXD respectively.

Using these waveforms, the definitions are as follows:
1. The transmitter output signal s and th e receiver input signals TD, TD, RD and RD each have a peak-to-peak voltage
(VPP) swing of A – B.
2. The differential output signal of the transmitter, VOD, is defined as VTD – VTD.
3. The differential input signal of the receiver, VID, is defined as VRD – VRD.
4. The differential output s ignal of the transmitter and the d ifferential input s ignal of the receiver each range fro m A – B
to –(A – B).
5. The peak value of the differential transmitter output signal and the differential receiver input signal is A – B.
6. The value of the differential transmitter output signal and the differential receiver input signal is 2 ×(A – B) VPP.
T o illustrate these definitions using real values, consider the case of a CML (Current Mode Logic) transmitter that has a common
mode voltage of 2 .25 V and each of its outputs, TD and TD , has a s wing that goes between 2.5 V and 2.0 V. Using these va lues,
the peak-to-peak vo ltag e swing of the signals TD and TD is 500 mVPP. The differential output signal ranges between 500 mV
and –500 mV. The peak differential voltage is 500 mV. The peak-to-peak differential voltage is 1000 mVPP.
Note: AC electrical specifications are given for transmitter and receiver. Long run and short run interfaces at three baud
rates (a total of six cases) are described. The parameters for the AC electrical specifications are guided by the XAUI
electrical interface specified in Clause 47 of IEEE™ Std 802.3ae-2002™. XAUI has similar application goals to
serial RapidIO. The goal of this standard is that electrical designs for serial RapidIO can reuse electrical designs for
XAUI, suitably modified for applications at the baud intervals and reaches described herein.
2.6.5.3 Equalization
W ith the use of high speed serial links, the interconnect media will cause degradation of the signal at the receiver. Effects such
as Inter-Symbol Interference (ISI) or data dependent jitter are produced. This loss can be large enough to degrade the eye
opening at the receiver beyond what is allowed in the specification. To negate a portion of these effects, equalization can be
used. The most common equalization techniques that can be used are:
• A passive high pass filter network placed at the receiver. This is often referred to as passive equalization.
• The use of active circuits in the receiver. This is often referred to as adaptive equalization.
2.6.5.4 Transmitter Specifications
LP-Serial transmitter electrical and timing sp ecifications are stated in the text an d tab les of th is section. The differential return
loss, S11, of the transmitter in each case shall be better than
• –10 dB for (baud frequency)/10 < freq(f) < 625 MHz, and
• –10 dB + 10log(f/625 MHz) dB for 625 MHz ≤ freq(f) ≤ baud frequency
The reference impedance for the differential return loss measurements is 1 00 Ω resistive. Differential return loss includes
contributions from internal circuitry, packaging, and any external components related to the driver. The output impedance
requirement applies to all valid output levels. It is recommended that the 20–80% rise/fall time of the transmitter, as measured
at the transmitter output, have a minimum value 60 ps in each case. It is also recommended that the timing skew at the output
of an LP-Serial transmitter between the two signals comprising a differential pair not exceed 25 ps at 1.25 GB, 20 ps at 2.50
GB, and 15 ps at 3.125 GB.

2.6.5.6 Receiver Eye Diagrams
For each bau d rate at which an LP-Serial receiv er is specified to oper ate, the receiver shall meet the correspondin g bit error rate
specification (Table 32, Table 33, and Table 34) when the eye pattern of the receiver test signal (exclusive of sinusoidal jitter)
falls entirely within the unshaded portion of the receiver input compliance mask shown in Figure 14 with the parameters
specified in Table 35. The eye pattern of the receiver test signal is measured at the input pins of the receiving device with the
device replaced with a 100 Ω ±5% differential resistive load.
2.6.5.7 Measurement and Test Requirements
Since the LP-Serial electrical specification are guided by the XAUI electrical interface specified in Clause 47 of IEEE Std.
802.3ae-20 02™, the measurement and tes t requirements defined her e are similarly guided by C lause 47. In addition, the CJPAT
test pattern defined in Annex 48A of IEEE Std. 802.3ae-2002 is specified as the test pattern for use in eye pattern and jitter
measurements. Annex 48B of IEEE Std. 802.3ae-2002 is recommended as a reference for additional information on jitter test
methods.

2.6.5.8 Eye Template Measurements
For the purpose of eye template measurements, the effects of a single-pole high pass filter with a 3 dB point at (baud
frequency)/1667 is applied to the jitter . The data pattern for template measurements is the continuous jitter test pattern (CJPAT)
defined in Annex 48A of IEEE Std. 802.3ae. All lanes of the LP-Serial link shall be active in both the transmit and receive
directions , and oppo site ends of the l inks shall us e asynchronou s clocks . Four lan e implementat ions shall u se CJPAT as defined
in Annex 48 A. Sing le lan e impl ementa ti ons sh al l use the CJ PAT sequence specifi ed in A nne x 48A fo r trans mi ssi on on la ne 0.
The amount of data represented in the eye shall be adequate to ensure that the bit error ratio is less than 10–12. The eye pattern
shall be measured with AC couplin g and the compliance template centered at 0 Volts differential. The left and right edges of
the template shall be aligned with the mean zero crossing points of the measured data eye. The load for this test shall be 100 Ω
resistive ±5% differential to 2.5 GHz.
2.6.5.9 Jitter Test Measurements
For the purpo se of jitter measurement , the effects of a sing le-pole high pass filter with a 3 dB point at (baud frequency)/16 67 is
applied to the jitter. The data pattern for jitter measurements is the Con tinuous Jitter Test Pattern (CJPAT) pattern defined in
Annex 48A of IEEE Std. 802.3 ae. All lanes of the LP-Serial link shall be active in both th e transmit and receive directions, and
opposi te ends of the link s shall use asynchron ous cloc ks. Four lane impl ementations shall use CJPAT as defined i n Annex 48 A.
Single lane implementat ions shall use the CJPAT sequ ence specif ied in Annex 48A for transmis sion on lane 0. Jitter shall be
measured with AC coupling and at 0 V differential. Jitter measurement for the transmitter (or for calibration of a jitter tolerance
setup) shall be performed with a test procedure result ing in a BER curve such as that described in Annex 48B of IEEE Std.
802.3ae.
2.6.5.10 Transmit Jitter
Transmit jitter is measured at the driver output wh en terminated into a load of 100 Ω resistive ±5% differential to 2.5 GHz.
2.6.5.11 Jitter Tolerance
Jitter tolerance is measured at the receiver using a jitter tolerance test signal. This signal is obtained by first producing the sum
of deterministic and random jitter defined in Section 2.6.5.9 and then adjusting the signal amplitude until the data eye contacts
the 6 points of the minimum eye op ening of the receiv e template s hown in Fig ure 14 and Table 35. Note that for this to occur,
the test signal must have vertical waveform symmetry about the average value and have horizontal symmetry (including jitter)
about the mean zero crossing. Eye template measurement requ irements are as defined above. Random jitter is calibrated using
a high pass filter with a low frequency corner at 20 MHz and a 20 dB/decade roll-off below this. The required sinusoidal jitter
specified in Section 8.6 is then added to the signal and the test load is replaced by the receiver being tested.

Notes: 1. Program the ETHMDC frequency (fMDC) to a maximum value of 2.5 MHz (400 ns period for tMDC). The value depends on the

3 Hardware Des ign Considerations
The following sections discuss areas to consider when the MSC8144EC device is designed into a system.
3.1 Start-up Sequencing Recommendations
3.1.1 Power-on Sequence
Use the following guidelines for power-on sequencing:
• There are no dependencies in power-on/power-off sequence between VDDM3 and VDD supplies.
• There are no dependencies in power-on/power-off sequence between RapidIO supplies: VDDSXC, VDDSXP,
VDDRIOPLL and other MSC8144EC supplies.
•V
DDPLL should be coupled with the VDD power rail with extremely low impedance path.
External voltage applied to any input line must not exceed the related to this port I/O supply by more than 0.6 V at any time,
including during power-up. Some designs require pull-up voltages applied to selected input lines during power-up for
configuration purposes. This is an acceptable exception to the rule during start-up. However , each such input can draw up to 80
mA per input pin per MSC8144EC device in the system during start-up. An assertion of the inputs to the high voltage level
before power-up should be with slew rate less th an 4V/ns.

Note: 1. This recommended power sequencing is different from the MSC8122/MSC8126.
2. If no pins that require VDDGE1 as a reference supply are used (see Table 1), VDDGE1 can be tied to GND.
3. If no pins that require VDDGE2 as a reference supply are used (see Table 1), VDDGE2 can be tied to GND.
4. If the DDR interface is not used, VDDDDR and MVREF can be tied to GND.
5. If the M3 memory is not used, VDDM3, VDDM3IO, and V25M3 can be tied to GND.
6. If the RapidIO interface is not used, VDDSX, VDDSXP, and VDDRIOPLL can be tied to GND.
3.1.2 Start-Up Timing
Section 2.7.1 describes the start-up tim ing.
3.2 Power Supply Design Considerations
Each PLL supply must have an external RC filter for the VDDPLL input. The filter is a 10 Ω resistor in series with two 2.2 μF,
low ESL (<0.5 nH) and low ESR capacitors. All three PLLs can connect to a single supply voltage source (such as a voltage
regulator) as long as the external RC filter is applied to each PLL separately (see Figure 45). For optimal noise filtering, place
the circuit as close as possible to its VDDPLL inputs. These traces should be short and direct.

3.3 Clock and Timing Signal Board Layout Considerations
When laying out the system board, use the following guidelines:
• Keep clock and timing signal paths as short as possible and route with 50 Ω impedance.
• Use a serial termination resistor placed close to the clock buffer to minimize signal reflection. Use the following
equation to compute the resist or value:
Rterm = Rim – Rbuf
where Rim = trace characteristic impedance
Rbuf = clock buffer internal impedance.
Note: See MSC8144 CLKIN and PCI_CLK_IN Board Layout (AN3440) for an example layout.
3.4 Connectivity Guidelines
Note: Although the package actually uses a ball grid array, the more conventional term pin is used to denote signal
connections in this discussion.
First, select the pin multiplexing mode to allocate the requir e d I/O signals. Then use the guidelin es p resented in the following
subsection s for board design a nd conn ections . The fo llowing convent ions ar e used in descr ibing the co nnectivity requiremen ts:
1. GND indicates using a 10 kΩ pull-down resistor (recommended) or a direct connection to the ground plane. Direct
connection s to t he gr oun d plane may yield DC current up to 50 mA th rou gh t he I/O su ppl y t hat add s to ov eral l pow er
consumption.
2. VDD indicates using a 10 kΩ pull-up resistor (recommended) or a direct connection to the appropriate power supply.
Direct connections to the supply may y ield DC cur rent u p to 5 0mA t h rou gh the I/O su ppl y t hat ad ds t o over a ll po wer
consumption.
3. Mandatory use of a pull-up or pull-down resistor it is clearly indicated as “pull-up/pull-down”.
4. NC indicates “not connected” and means do not connect anything to the pin.
