electrical characteristics mpc8610 integrated host processor hardware specifications, rev. 2 freescale semiconductor 55 of differential swing in amplitude, or twice of the differential peak. for example, the output differential peak-peak voltage can also be calculated as v tx-diffp-p = 2 * |v od |. 6. differential waveform the differential waveform is constructed by subtracting the inverting signal (sd n _tx , for example) from the noninverting signal (sd n _tx, for example) within a differential pair. there is only one signal trace curve in a differential waveform. the voltage represented in the differential waveform is not referenced to ground. refer to figure 38 as an example for differential waveform. 7. common mode voltage, v cm the common mode voltage is equal to one half of the sum of the voltages between each conductor of a balanced interchange circuit and ground. in this example, for serdes output, v cm_out = (v sd n _tx + v sd n _tx )/2 = (a + b)/2, which is the arithmetic mean of the two complimentary output voltages within a differential pair. in a system, the common mode voltage may often differ from one component?s output to the other?s input. sometimes, it may be even different between the receiver input and driver output circuits within the same component. it?s also referred as the dc offset in some occasion. figure 29. differential voltage definitions for transmitter or receiver to illustrate these definitions using real values, consider the case of a cml (current mode logic) transmitter that has a commo n mode voltage of 2.25 v and each of its outputs, td and td , has a swing that goes between 2.5 and 2.0 v. using these values, the peak-to-peak voltage swing of each signal (td or td ) is 500 mv p-p, which is referred as the single-ended swing for each signal. in this example, since the differential signaling environment is fully symmetrical, the transmitter output?s differenti al swing (v od ) has the same amplitude as each signal?s single-ended swing. the differential output signal ranges between 500 mv and ?500 mv, in other words, v od is 500 mv in one phase and ?500 mv in the other phase. the peak differential voltage (v diffp ) is 500 mv. the peak-to-peak differential voltage (v diffp-p ) is 1000 mv p-p. 2.17.2 serdes reference clocks the serdes reference clock inputs are applied to an internal pll whose output creates the clock used by the corresponding serdes lanes. the serdes reference clocks inputs are sd n _ref_clk and sd n _ref_clk for pci express. the following sections describe the serdes reference clock requirements and some application information. 2.17.2.1 serdes reference clock receiver characteristics figure 30 shows a receiver reference diagram of the serdes reference clocks. ? the supply voltage requirements for x n v dd are specified in table 2 and table 3 . differential swing, v id or v od = a ? b a volts b volts sd n _tx or sd n _rx sd n _tx or sd n _rx differential peak voltage, v diffp = |a ? b| differential peak-peak voltage, v diffpp = 2*v diffp (not shown) v cm = (a + b) / 2

electrical characteristics mpc8610 integrated host processor hardware specifications, rev. 2 freescale semiconductor 57 ? for external ac-coupled connection, there is no common mode voltage requirement for the clock driver. since the external ac-coupling capacitor blocks the dc level, the clock driver and the serdes reference clock receiver operate in different command mode voltages. the serdes reference clock receiver in this connection scheme has its common mode voltage set to sgnd. each signal wire of the differential inputs is allowed to swing below and above the command mode voltage (sgnd). figure 32 shows the serdes reference clock input requirement for ac-coupled connection scheme. ? single-ended mode ? the reference clock can also be single-ended. the sd n _ref_clk input amplitude (single-ended swing) must be between 400 and 800 mv peak-peak (from v min to v max ) with sd n _ref_clk either left unconnected or tied to ground. ?the sd n _ref_clk input average voltage must be between 200 and 400 mv. figure 33 shows the serdes reference clock input requirement for single-ended signaling mode. ? to meet the input amplitude requirement, the reference clock inputs might need to be dc- or ac-coupled externally. for the best noise performance, the reference of the clock could be dc- or ac-coupled into the unused phase (sd n _ref_clk ) through the same source impedance as the clock input (sd n _ref_clk) in use. figure 31. differential reference clock input dc requirements (external dc-coupled) figure 32. differential reference clock input dc requirements (external ac-coupled) figure 33. single-ended reference clock input dc requirements sd n _ref_clk sd n _ref_clk v max < 800 mv v min > 0v 100 mv < v cm < 400 mv 200 mv < input amplitude or differential peak < 800 mv sd n _ref_clk sd n _ref_clk sd n _ref_clk v cm 200mv < input amplitude or differential peak < 800 mv v max < v cm + 400 mv v min > v cm ? 400 mv sd n _ref_clk sd n _ref_clk 400 mv < sd n _ref_clk input amplitude < 800 mv 0 v
mpc8610 integrated host processor hardware specifications, rev. 2 electrical characteristics freescale semiconductor 58 2.17.2.3 interfacing with other differential signaling levels ? with on-chip termination to sgnd, the differential reference clocks inputs are hcsl (high-speed current steering logic) compatible dc-coupled. ? many other low voltage differential type outputs like lvds (low voltage differential signaling) can be used but may need to be ac-coupled due to the limited common mode input range allowed (100 to 400 mv) for dc-coupled connection. ? lvpecl outputs can produce signal with too large amplitude and may need to be dc-biased at clock driver output first, then followed with series attenuation resistor to reduce the amplitude, in addition to ac-coupling. note figure 34 to figure 37 are for conceptual reference only. due to the fact that clock driver chip's internal structure, output impedance and termination requirements are different between various clock driver chip manufacturers, it is very possible that the clock circuit reference designs provided by clock driver chip vendor are different from what is shown below. they might also vary from one vendor to the other. therefore, freescale semiconductor can neither provide the optimal clock driver reference circuits nor guarantee the correctness of the following clock driver connection reference circuits. the system designer is recommended to contact the selected clock driver chip vendor for the optimal reference circuits with the mpc8610 serdes reference clock receiver requirement provided in this document. figure 34 shows the serdes reference clock connection reference circuits for hcsl type clock driver. it assumes that the dc levels of the clock driver chip is compatible with mpc8610 serdes reference clock input?s dc requirement. figure 34. dc-coupled differential connection with hcsl clock driver (reference only) figure 35 shows the serdes reference clock connection reference circuits for lvds type clock driver. since lvds clock driver?s common mode voltage is higher than the mpc8610 serdes reference clock input?s allowed range (100 to 400 mv), ac-coupled connection scheme must be used. it assumes the lvds output driver features 50- termination resistor. it also assumes that the lvds transmitter establishes its own common mode level without relying on the receiver or other external component. 50 50 sd n _ref_clk sd n _ref_clk clock driver 100 differential pwb trace clock driver vendor dependent source termination resistor clk_out clk_out hcsl clk driver chip 33 33 total 50 . assume clock driver?s output impedance is about 16 . mpc8610 clk_out serdes refer. clk receiver clock driver

hardware design considerations mpc8610 integrated host processor hardware specifications, rev. 2 freescale semiconductor 77 note the following: ?sd n av dd should be a filtered version of sv dd . ? signals on the serdes interface are fed from the sv dd power plane. 3.3 decoupling recommendations due to large address and data buses, and high operating frequencies, the device can generate transient power surges and high frequency noise in its power supply, especially while driving large capacitive loads. this noise must be prevented from reachin g other components in the mpc8610 system, and the device itself requires a clean, tightly regulated source of power. therefore, it is recommended that the system designer place at least one decoupling capacitor at each v dd , bv dd , ov dd , gv dd , v dd _core, and v dd _plat pin of the device. these decoupling capacitors should receive their power from separate v dd, bv dd , ov dd , gv dd , v dd _core, v dd _plat, and gnd power planes in the pcb, utilizing short traces to minimize inductance. capacitors may be placed directly under the device using a standard escape pattern. others may surround the part. these capacitors should have a value of 0.01 or 0.1 f. only ceramic smt (surface mount technology) capacitors should be used to minimize lead inductance, preferably 0402 or 0603 sizes. in addition, it is recommended that there be several bulk storage capacitors distributed around the pcb, feeding the v dd , bv dd , ov dd , gv dd , v dd _core, and v dd _plat planes, to enable quick recharging of the smaller chip capacitors. these bulk capacitors should have a low esr (equivalent series resistance) rating to ensure the quick response time necessary. they should also be connected to the power and ground planes through two vias to minimize inductance. suggested bulk capacitors?100?330 f (avx tps tantalum or sanyo oscon). 3.4 serdes block power supply decoupling recommendations the serdes block requires a clean, tightly regulated source of power (s n v dd and x n v dd ) to ensure low jitter on transmit and reliable recovery of data in the receiver. an appropriate decoupling scheme is outlined below. only surface mount technology (smt) capacitors should be used to minimize inductance. connections from all capacitors to power and ground should be done with multiple vias to further reduce inductance. ? first, the board should have at least 10 x 10-nf smt ceramic chip capacitors as close as possible to the supply balls of the device. where the board has blind vias, these capacitors should be placed directly below the chip supply and ground connections. where the board does not have blind vias, these capacitors should be placed in a ring around the device as close to the supply and ground connections as possible. ? second, there should be a 1-f ceramic chip capacitor on each side of the device. this should be done for all serdes supplies. ? third, between the device and any serdes voltage regulator there should be a 10-f, low equivalent series resistance (esr) smt tantalum chip capacitor and a 100-f, low esr smt tantalum chip capacitor. this should be done for all serdes supplies. 3.5 connection recommendations to ensure reliable operation, it is highly recommended to connect unused inputs to an appropriate signal level. all unused acti ve low inputs should be tied to v dd , bv dd , ov dd , gv dd , v dd _core, v dd _plat, x n v dd , and s n v dd as required. all unused active high inputs should be connected to gnd. all nc (no-connect) signals must remain unconnected. power and ground connections must be made to all external v dd , bv dd , ov dd , gv dd , v dd _core, v dd _plat, x n v dd , s n v dd , and gnd pins of the device. special cases: ? local bus?if parity is not used, tie ldp[0:3] to ground via a 4.7-k resistor, tie lpbse to ov dd via a 4.7-k resistor (pull-up resistor). for systems which boot from local bus (gpcm)-controlled flash, a pull up on lgpl4 is required.

mpc8610 integrated host processor hardware specifications, rev. 2 hardware design considerations freescale semiconductor 80 3.9 jtag configuration signals correct operation of the jtag interface requires configuration of a group of system control pins as demonstrated in figure 53 . care must be taken to ensure that these pins are maintained at a valid deasserted state under normal operating conditions as mo st have asynchronous behavior and spurious assertion will give unpredictable results. boundary-scan testing is enabled through the jtag interface signals. the trst signal is optional in the ieee 1149.1 specification, but is provided on all processors that implement the power architecture technology. the device requires trst to be asserted during reset conditions to ensure the jtag boundary logic does not interfere with normal chip operation. while it is possible to force the tap controller to the reset state using only the tck and tms signals, more reliable power-on reset performance will be obtained if the trst signal is asserted during power-on reset. because the jtag interface is also used for accessing the common on-chip processor (cop) function, simply tying trst to hreset is not practical. the cop function of these processors allows a remote computer system (typically a pc with dedicated hardware and debugging software) to access and control the internal operations of the processor. the cop port connects primarily through the jtag interface of the processor, with some additional status monitoring signals. the cop port requires the ability to independently assert hreset or trst in order to fully control the processor. if the target system has independent reset sources, such as voltage monitors, watchdog timers, power supply failures, or push-button switches, then the cop reset signals must be merged into these signals with logic. the arrangement shown in figure 52 allows the cop port to independently assert hreset or trst , while ensuring that the target can drive hreset as well. the cop interface has a standard header, shown in figure 52 , for connection to the target system, and is based on the 0.025" square-post, 0.100" centered header assembly (often called a berg header). the connector typically has pin 14 removed as a connector key. the cop header adds many benefits such as breakpoints, watchpoints, register and memory examination/modification, and other standard debugger features. an inexpensive option can be to leave the cop header unpopulated until needed. there is no standardized way to number the cop header shown in figure 53 ; consequently, many different pin numbers have been observed from emulator vendors. some are numbered top-to-b ottom then left-to-right, while others use left-to-right then top-to-bottom, while still others number the pins counter clockwise from pin 1 (as with an ic). regardless of the numbering, the signal placement recommended in figure 53 is common to all known emulators. 3.9.1 termination of unused signals if the jtag interface and cop header will not be used, freescale recommends the following connections: ?trst should be tied to hreset through a 0-k isolation resistor so that it is asserted when the system reset signal (hreset ) is asserted, ensuring that the jtag scan chain is initialized during the power-on reset flow. freescale recommends that the cop header be designed into the system as shown in figure 53 . if this is not possible, the isolation resistor will allow future access to trst in case a jtag interface may need to be wired onto the system in future debug situations. ?tie tck to ov dd through a 10-k resistor. this will prevent tck from changing state and reading incorrect data into the device. ? no connection is required for tdi, tms, or tdo.

hardware design considerations mpc8610 integrated host processor hardware specifications, rev. 2 freescale semiconductor 85 to reduce the die-junction temperature, heat sinks are required; due to the potential large mass of the heat sink, attachment through the printed-circuit board is suggested. in any implementation of a heat sink solution, the force on the die should not exceed ten pounds force (45 newtons). figure 54 shows a spring clip through the board. occasionally the spring clip is attached to soldered hooks or to a plastic backing structure. screw and spring arrangements are also frequently used. figure 54. fc-pbga package exploded cross-sectional view with several heat sink options suitable heat sinks are commercially available from the following vendors: aavid thermalloy 603-224-9988 80 commercial st. concord, nh 03301 internet: www.aavidthermalloy.com advanced thermal solutions 781-769-2800 89 access road #27. norwood, ma02062 internet: www.qats.com alpha novatech 408-749-7601 473 sapena ct. #12 santa clara, ca 95054 internet: www.alphanovatech.com calgreg thermal solutions 888-732-6100 60 alhambra road, suite 1 warwick, ri 02886 internet: www.calgreg.com international electronic research corporation (ierc) 818-842-7277 413 north moss st. burbank, ca 91502 internet: www.ctscorp.com millennium electronics (mei) 408-436-8770 loroco sites 671 east brokaw road san jose, ca 95112 internet: www.mei-thermal.com thermal heat sink fc-pbga package heat sink clip printed-circuit board interface material
