Low Voltage PLL Clock Driver
The MPC953 is a 3.3V compatible, PLL based clock driver device
targeted for high performance clock tree designs. With output frequencies
of up to 110MHz and output skews of 150ps the MPC953 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.

100ps Cycle–to–Cycle Jitter
The MPC953 has a differential LVPECL reference input along with an
external feedback input. These features make the MPC953 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 reset the internal counters and tristate the output buffers when
driven “high”.
The MPC953 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. For series terminated
50
lines, each of the MPC953 outputs can drive two traces giving the
device an effective fanout of 1:18. The device is packaged in a 7x7mm
32–lead LQFP package to provide the optimum combination of board
density and performance.
