The MPC9658 is specified for the temperature range of 0°C to +70°C.

Normal operation of the MPC9658 requires 32 LEAD LQFP PACKAGE CASE 873A the connection of the QFB output to the feedback input to close the PLL feedback path (external feedback). With the PLL locked, the output frequency is equal to the reference frequency of the device and VCO_SEL selects the operating frequency range of 50 to 125 MHz or 100 to 250 MHz. The two available post-PLL dividers selected by VCO_SEL (divide-by-2 or divide-by-4) and the reference clock frequency determine the VCO frequency. Both must be selected to match the VCO frequency range. The internal VCO of the MPC9658 is running at either 2x or 4x of the reference clock frequency. The MPC9658 has a differential LVPECL reference input along with an external feedback input. The MPC9658 is ideal for use as a zero delay, low skew fanout buffer. The device performance has been tuned and optimized for zero delay performance. The PLL_EN and BYPASS controls select the PLL bypass configuration for test and diagnosis. In this configuration, the selected input reference clock is bypassing the PLL and routed either to the output dividers or directly to the outputs. The PLL bypass configurations are fully static and the minimum clock frequency specification and all other PLL characteristics do not apply. The outputs can be disabled (high-impedance) and the device reset by asserting the MR/OE pin. Asserting MR/OE also causes the PLL to loose lock due to missing feedback signal presence at FB_IN. Deasserting MR/OE will enable the outputs and close the phase locked loop, enabling the PLL to recover to normal operation. The MPC9658 is fully 3.3V compatible and requires no external loop filter components. The inputs (except PCLK) accept LVCMOS except signals while the outputs provide LVCMOS compatible levels with the capability to drive terminated 50 transmission lines. For series terminated transmission lines, each of the MPC9658 outputs can drive one or two traces giving the devices an effective fanout of 1:16. The device is packaged in a 7x7 mm2 32-lead LQFP package. W Motorola, Inc. 2003 For More Information On This Product, 1 Go to: www.freescale.com Freescale Semiconductor, Inc.

MPC9658 APPLICATIONS INFORMATION Programming the MPC9658 The MPC9658 supports output clock frequencies from 50 to 250 MHz. Two different feedback divider configurations can be used to achieve the desired frequency operation range. The feedback divider (VCO_SEL) should be used to situate the VCO in the frequency lock range between 200 and 500 MHz for stable and optimal operation. Two operating frequency ranges are supported: 50 to 125 MHz and 100 to 250 MHz. Table 7 illustrates the configurations supported by the MPC9658. PLL zero-delay is supported if BYPASS=1, PLL_EN=1 and the input frequency is within the specified PLL reference frequency range. Freescale Semiconductor, Inc... Table 7.

Its analog circuitry is naturally susceptible to random noise, especially if this noise is seen on the power supply pins. Random noise on the VCCA_PLL power supply impacts the device characteristics, for instance I/O jitter. The MPC9658 provides separate power supplies for the output buffers (VCC) and the phase-locked loop (VCCA_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 VCC_PLL pin for the MPC9658. Figure 3. illustrates a typical power supply filter scheme. The MPC9658 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 12 mA (20 mA maximum), assuming that a minimum of 2.835V must be maintained on the VCC_PLL pin. MOTOROLA Ratio Output range (fQ0-9) VCO fQ0-9 = fREF fQ0-9 = fREF ÷ 2 0-250 MHz n/a 0-125 MHz n/a RF = 5–15Ω CF = 22 µF RF VCC_PLL VCC CF 10 nF MPC9658 VCC 33...100 nF Figure 3. VCC_PLL Power Supply Filter 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 3. “VCC_PLL Power Supply Filter”, the filter cut-off frequency is around 3-5 kHz and the noise attenuation at 100 kHz is better than 42 dB. As the noise frequency crosses the series resonant point of an individual capacitor its overall impedance begins to look inductive and thus increases with increasing frequency. 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 MPC9658 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.

Confidence Facter CF Nested clock trees are typical applications for the MPC9658. Designs using the MPC9658 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 MPC9658 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. Calculation of part-to-part skew The MPC9658 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 MPC9658 are connected together, the maximum overall timing uncertainty from the common PCLK input to any output is: tSK(PP) = t( ∅) + tSK(O) + tPD, LINE(FB) + tJIT( ∅) tPD,LINE(FB) –t(∅) Probability of clock edge within the distribution ± 1s 0.68268948 ± 2s 0.95449988 ± 3s 0.99730007 ± 4s 0.99993663 ± 5s 0.99999943 ± 6s 0.99999999 The feedback trace delay is determined by the board layout and can be used to fine-tune the effective delay through each device. In the following example calculation a I/O jitter confidence factor of 99.7% (± 3s) is assumed, resulting in a worst case timing uncertainty from input to any output of -214 ps to 224 ps relative to PCLK (fREF = 100 MHz, FB=÷4, tjit(∅)=8 ps RMS at fVCO = 400 MHz): tSK(PP) = [–70ps...80ps] + [–120ps...120ps] + [(8ps @ –3)...(8ps @ 3)] + tPD, LINE(FB) tSK(PP) = [–214ps...224ps] + tPD, LINE(FB) Due to the frequency dependence of the I/O jitter, figure 5. can be used for a more precise timing performance analysis.

TIMING SOLUTIONS Driving Transmission Lines The MPC9658 clock driver was designed to drive high speed signals in a terminated transmission line environment. To provide the optimum flexibility to the user the output drivers were designed to exhibit the lowest impedance possible. With an output impedance of less than 20Ω the drivers can drive either parallel or series terminated transmission lines. For more information on transmission lines the reader is referred to Motorola application note AN1091. In most high performance clock networks point-to-point distribution of signals is the method of choice. In a point-to-point scheme either series terminated or parallel terminated transmission lines can be used. The parallel technique terminates the signal at the end of the line with a 50Ω resistance to VCC÷2. This technique draws a fairly high level of DC current and thus only a single terminated line can be driven by each output of the MPC9658 clock driver. For the series terminated case however there is no DC current draw, thus the outputs can drive multiple series terminated lines. Figure 6. “Single For More Information On This Product, 7 Go to: www.freescale.com MOTOROLA Freescale Semiconductor, Inc. MPC9658 versus Dual Transmission Lines” illustrates an output driving a single series terminated line versus two series terminated lines in parallel. When taken to its extreme the fanout of the MPC9658 clock driver is effectively doubled due to its capability to drive multiple lines. towards the quiescent 3.0V in steps separated by one round trip delay (in this case 4.0ns). 3.0 OutA tD = 3.8956 MPC9658 OUTPUT BUFFER IN RS = 36Ω 14Ω OutA Freescale Semiconductor, Inc...

Single versus Dual Waveforms Figure 6. Single versus Dual Transmission Lines The waveform plots in Figure 7. “Single versus Dual Line Termination Waveforms” show the simulation results of an output driving a single line versus two lines. In both cases the drive capability of the MPC9658 output buffer is more than sufficient to drive 50Ω transmission lines on the incident edge. Note from the delay measurements in the simulations a delta of only 43ps exists between the two differently loaded outputs. This suggests that the dual line driving need not be used exclusively to maintain the tight output-to-output skew of the MPC9658. The output waveform in Figure 7. “Single versus Dual Line Termination Waveforms” shows a step in the waveform, this step is caused by the impedance mismatch seen looking into the driver. The parallel combination of the 36Ω series resistor plus the output impedance does not match the parallel combination of the line impedances. The voltage wave launched down the two lines will equal: = VS ( Z0 ÷ (RS+R0 +Z0)) = 50Ω || 50Ω = 36Ω || 36Ω = 14Ω = 3.0 ( 25 ÷ (18+14+25) = 1.31V At the load end the voltage will double, due to the near unity reflection coefficient, to 2.6V. It will then increment VL Z0 RS R0 VL Differential Pulse Generator Z = 50 ZO = 50 Ω Since this step is well above the threshold region it will not cause any false clock triggering, however designers may be uncomfortable with unwanted reflections on the line. To better match the impedances when driving multiple lines the situation in Figure 8. “Optimized Dual Line Termination” should be used. In this case the series terminating resistors are reduced such that when the parallel combination is added to the output buffer impedance the line impedance is perfectly matched.
