The MPC958 is a 3.3V compatible, PLL based clock driver device

targeted for high performance clock tree designs. With output frequencies

of up to 200MHz and output skews of 200ps the MPC958 is ideal for the

most demanding clock tree designs. The devices employ a fully

differential PLL design to minimize cycle–to–cycle and phase jitter.

LOW VOLTAGE

PLL CLOCK DRIVER

• Fully Integrated PLL

• Output Frequency up to 200MHz

• Outputs Disable in High Impedance

• LQFP Packaging

• 100ps Cycle–to–Cycle Jitter

The MPC958 has a differential LVPECL reference input along with an

external feedback input. These features make the MPC958 ideal for use

as a zero delay, low skew fanout buffer. The device performance has

been tuned and optimized for zero delay performance. The MR/OE input

pin will tristate the output buffers when driven “high”.

32–LEAD LQFP PACKAGE

CASE 873A–02

The MPC958 is fully 3.3V compatible and requires no external loop

filter components. All control inputs accept LVCMOS or LVTTL

compatible levels while the outputs provide LVCMOS levels with the

ability to drive terminated 50Ω transmission lines. For series terminated

50Ω lines, each of the MPC958 outputs can drive two traces giving the

device an effective fanout of 1:22. The device is packaged in a 7x7mm

32–lead LQFP package to provide the optimum combination of board

density and performance.
