Low Voltage Zero Delay Buffer
MPC961C
The MPC961 is a 2.5 V or 3.3 V compatible, 1:18 PLL based zero delay buffer. With output
frequencies of up to 200 MHz, output skews of 150 ps the device meets the needs of the most
demanding clock tree applications.

Functional Description
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 losing lock.
The MPC961 is fully 2.5 V or 3.3 V compatible and requires no external loop filter components. All control inputs accept LVCMOS compatible
levels and the outputs provide low impedance LVCMOS outputs capable of driving terminated 50
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.
