Low Voltage Zero Delay
Buffer
The MPC961 is a 2.5V or 3.3V compatible, 1:18 PLL based zero delay
buffer. With output frequencies of up to 200MHz, output skews of 150ps
the device meets the needs of the most demanding clock tree applica-
tions.

The MPC961 is offered with two different input configurations. The
MPC961C offers an LVCMOS reference clock while the MPC961P offers
an LVPECL reference clock.
When pulled high the OE pin will force all of the outputs (except QFB)
into a high impedance state. Because the OE pin does not affect the QFB
output, down stream clocks can be disabled without the internal PLL los-
ing lock.
The MPC961 is fully 2.5V or 3.3V compatible and requires no external
loop filter components. All control inputs accept LVCMOS compatible lev-
els and the outputs provide low impedance LVCMOS outputs capable of
driving terminated 50
W transmission lines. For series terminated lines the
MPC961 can drive two lines per output giving the device an effective
fanout of 1:36. The device is packaged in a 32 lead LQFP package to
provide the optimum combination of board density and performance.
