The MPC9952 is a 3.3V compatible, PLL based clock driver device

targeted for high performance clock tree applications. The device fea-

tures a fully integrated PLL with no external components required. With

output frequencies of up to 180MHz and eleven low skew outputs the

MPC9952 is well suited for high performance designs. The device em-

ploys a fully differential PLL design to optimize jitter and noise rejection

performance. Jitter is an increasingly important parameter as more micro-

processors and ASiC’s are employing on chip PLL clock distribution.

• Fully Integrated PLL

• Output Frequency up to 180MHz

• High Impedance Disabled Outputs

• Compatible with PowerPC, Intel and High Performance RISC Micro-

processors

• Output Frequency Configurable

• LQFP Packaging

100ps Cycle–to–Cycle Jitter

The MPC9952 features three banks of individually configurable out-

puts. The banks contain 5 outputs, 4 outputs and 2 outputs. The internal

divide circuitry allows for output frequency ratios of 1:1, 2:1, 3:1 and 3:2:1.

The output frequency relationship is controlled by the fsel frequency con-

trol pins. The fsel pins as well as the other inputs are LVCMOS/LVTTL

compatible inputs.

The MPC9952 uses external feedback to the PLL. This features allows

for the use of the device as a “zero delay” buffer. Any of the

eleven outputs can be used as the feedback to the PLL. The VCO_Sel

pin allows for the choice of two VCO ranges to optimize PLL stability and

jitter performance. The MR/OE pin allows the user to force the outputs

into high impedance for board level test.

For system debug the PLL of the MPC9952 can be bypassed. When forced to a logic HIGH, the PLLEN input will route the

signal on the RefClk input around the PLL directly to the internal dividers. Because the signal is routed through the dividers, it

may take several transitions of the RefClk to affect a transition on the outputs. This features allows a designer to single step the

design for debug purposes.

The outputs of the MPC9952 are LVCMOS outputs. The outputs are optimally designed to drive terminated transmission lines.

For applications using series terminated transmission lines each MPC9952 output can drive two lines. This capability provides an

effective fanout of 22, more than enough clocks for most clock tree designs. For more information on driving transmission lines

consult the applications section of this data sheet.
