 Freescale Semiconductor, Inc. SEMICONDUCTOR TECHNICAL DATA       The MPC97H73 is a 3.3V compatible, 1:12 PLL based clock generator targeted for high performance low-skew clock distribution in mid-range to high-performance networking, computing and telecom applications. With output frequencies up to 240 MHz and output skews less than 250 ps the device meets the needs of the most demanding clock applications. Features • 1:12 PLL based low-voltage clock generator Order Number: MPC97H73/D Rev 0, 10/2003   3.3V 1:12 LVCMOS PLL CLOCK GENERATOR Freescale Semiconductor, Inc... • 3.3V power supply • Internal power–on reset • Generates clock signals up to 240 MHz • Maximum output skew of 250 ps • Differential PECL reference clock input • Two LVCMOS PLL reference clock inputs • External PLL feedback supports zero-delay capability • Various feedback and output dividers (see application section) • Supports up to three individual generated output clock frequencies • Synchronous output clock stop circuitry for each individual output for FA SUFFIX 52 LEAD LQFP PACKAGE CASE 848D power down support • Drives up to 24 clock lines • Ambient temperature range 0°C to +70°C • Pin and function compatible to the MPC973 Functional Description The MPC97H73 utilizes PLL technology to frequency lock its outputs onto an input reference clock. Normal operation of the MPC97H73 requires the connection of the PLL feedback output QFB to feedback input FB_IN to close the PLL feedback path. The reference clock frequency and the divider for the feedback path determine the VCO frequency. Both must be selected to match the VCO frequency range. The MPC97H73 features an extensive level of frequency programmability between the 12 outputs as well as the output to input relationships, for instance 1:1, 2:1, 3:1, 3:2, 4:1, 4:3, 5:1, 5:2, 5:3, 5:4, 5:6, 6:1, 8:1 and 8:3. The QSYNC output will indicate when the coincident rising edges of the above relationships will occur. The selectability of the feedback frequency is independent of the output frequencies. This allows for very flexible programming of the input reference versus output frequency relationship. The output frequencies can be either odd or even multiples of the input reference. In addition the output frequency can be less than the input frequency for applications where a frequency needs to be reduced by a non–binary factor. The MPC97H73 also supports the 180° phase shift of one of its output banks with respect to the other output banks. The QSYNC outputs reflects the phase relationship between the QA and QC outputs and can be used for the generation of system baseline timing signals. The REF_SEL pin selects the LVPECL or the LVCMOS compatible inputs as the reference clock signal. Two alternative LVCMOS compatible clock inputs are provided for clock redundancy support. The PLL_EN control selects the PLL bypass configuration for test and diagnosis. In this configuration, the selected input reference clock is routed directly to the output dividers bypassing the PLL. The PLL bypass is fully static and the minimum clock frequency specification and all other PLL characteristics do not apply. The outputs can be individually disabled (stopped in logic low state) by programming the serial CLOCK_STOP interface of the MPC97H73. The MPC97H73 has an internal power–on reset. The MPC97H73 is fully 3.3V compatible and requires no external loop filter components. All inputs (except PCLK) accept LVCMOS signals while the outputs provide LVCMOS compatible levels with the capability to drive terminated 50 W transmission lines. For series terminated transmission lines, each of the MPC97H73 outputs can drive one or two traces giving the devices an effective fanout of 1:24. The device is pin and function compatible to the MPC973 and is packaged in a 52-lead LQFP package.  Motorola, Inc. 2003 For1 More Information On This Product, Go to: www.freescale.com Freescale Semiconductor, Inc.

MPC97H73 Individual Output Disable (Clock Stop) Circuitry MPC97H73 writing logic ‘0’ to the respective stop enable bit. Likewise, the user may programmably enable an output clock by writing logic ‘1’ to the respective enable bit. The clock stop logic enables or disables clock outputs during the time when the output would be in normally in logic low state, eliminating the possibility of short or ‘runt’ clock pulses. The user can write to the serial input register through the STOP_DATA input by supplying a logic ‘0’ start bit followed serially by 12 NRZ disable/enable bits. The period of each STOP_DATA bit equals the period of the free–running STOP_CLK signal. The STOP_DATA serial transmission should be timed so the MPC97H73 can sample each STOP_DATA bit with the rising edge of the free–running STOP_CLK signal. (see Figure 5. ) The individual clock stop (output enable) control of the MPC97H73 allows designers, under software control, to implement power management into the clock distribution design. A simple serial interface and a clock stop control logic provides a mechanism through which the MPC97H73 clock outputs can be individually stopped in the logic ‘0’ state: The clock stop mechanism allows serial loading of a 12–bit serial input register. This register contains one programmable clock stop bit for 12 of the 14 output clocks. The QC0 and QFB outputs cannot be stopped (disabled) with the serial port. The user can program an output clock to stop (disable) by Freescale Semiconductor, Inc...                 Figure 5.

MPC97H73 Power Supply Filtering Using the MPC97H73 in zero–delay applications The MPC97H73 is a mixed analog/digital product. Its analog circuitry is naturally susceptible to random noise, especially if this noise is seen on the power supply pins. Random noise on the VCC_PLL power supply impacts the device characteristics, for instance I/O jitter. The MPC97H73 provides separate power supplies for the output buffers (VCC) and the phase-locked loop (VCC_PLL) of the device. The purpose of this design technique is to isolate the high switching noise digital outputs from the relatively sensitive internal analog phase-locked loop. In a digital system environment where it is more difficult to minimize noise on the power supplies a second level of isolation may be required. The simple but effective form of isolation is a power supply filter on the VCCA_PLL pin for the MPC97H73. Figure 7. illustrates a typical power supply filter scheme. The MPC97H73 frequency and phase stability is most susceptible to noise with spectral content in the 100kHz to 20MHz range. Therefore the filter should be designed to target this range. The key parameter that needs to be met in the final filter design is the DC voltage drop across the series filter resistor RF. From the data sheet the ICC_PLL current (the current sourced through the VCC_PLL pin) is typically 8 mA (13.5 mA maximum), assuming that a minimum of 3.0V must be maintained on the VCC_PLL pin. The resistor RF shown in Figure 7. “VCC_PLL Power Supply Filter” must have a resistance of 5-10W to meet the voltage drop criteria. Nested clock trees are typical applications for the MPC97H73. Designs using the MPC97H73 as LVCMOS PLL fanout buffer with zero insertion delay will show significantly lower clock skew than clock distributions developed from CMOS fanout buffers. The external feedback option of the MPC97H73 clock driver allows for its use as a zero delay buffer. The PLL aligns the feedback clock output edge with the clock input reference edge resulting a near zero delay through the device (the propagation delay through the device is virtually eliminated). The maximum insertion delay of the device in zero-delay applications is measured between the reference clock input and any output. This effective delay consists of the static phase offset, I/O jitter (phase or long-term jitter), feedback path delay and the output-to-output skew error relative to the feedback output.  < 7Ω The MPC97H73 zero delay buffer supports applications where critical clock signal timing can be maintained across several devices. If the reference clock inputs of two or more MPC97H73 are connected together, the maximum overall timing uncertainty from the common CCLKx input to any output is: tSK(PP) = t( ∅) + tSK(O) + tPD, LINE(FB) + tJIT( ∅)  CF  <  µ  Calculation of part-to-part skew This maximum timing uncertainty consist of 4 components: static phase offset, output skew, feedback board trace delay and I/O (phase) jitter:    %   === %  ,GG,% Figure 7. VCC_PLL Power Supply Filter */$6*  The minimum values for RF and the filter capacitor CF are defined by the required filter characteristics: the RC filter should provide an attenuation greater than 40 dB for noise whose spectral content is above 100 kHz. In the example RC filter shown in Figure 7. “VCC_PLL Power Supply Filter”, the filter cut-off frequency is around 4.5 kHz and the noise attenuation at 100 kHz is better than 42 dB.

The parallel capacitor combination shown ensures that a low impedance path to ground exists for frequencies well above the bandwidth of the PLL. Although the MPC97H73 has several design features to minimize the susceptibility to power supply noise (isolated power and grounds and fully differential PLL) there still may be applications in which overall performance is being degraded due to system power supply noise. The power supply filter schemes discussed in this section should be adequate to eliminate power supply noise related problems in most designs.
