The MPC954 is a 3.3V compatible, PLL based zero delay buffer
targeted for high performance clock tree designs. With 11 outputs at
frequencies of up to 125MHz and output skews of 200ps the MPC954 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.

Output Frequency up to 125MHz in PLL Mode
Outputs Disable in High Impedance
TQFP Packaging
50ps Cycle–to–Cycle Jitter
The analog VCC pin of the device also serves as a PLL bypass select
pin. When driven low the AVCC pin will route the REF_CLK input around
the PLL directly to the outputs. The OE input is a logic enable for all of the
outputs except QFB. A low on the OE pin forces Q0–Q9 to a logic low
state.
The MPC954 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 50
transmission lines. The output impedance
of the MPC954 is
10 , therefore for series terminated 50
lines, each
of the MPC954 outputs can drive two traces giving the device an effective
fanout of 1:22. The device is packaged in a 24–lead TSSOP package to
provide the optimum combination of board density and performance.
