Functional Description
The MPC961 is offered with two different input configurations. The MPC961P
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 termi-
nated lines the MPC961 can drive two lines per output giving the device an ef-
fective fanout of 1:36. The device is packaged in a 32 lead LQFP package to
provide the optimum combination of board density and performance.
