3.3V/2.5V 1:9 LVCMOS Clock
Fanout Buffer
The MPC9447 is a 3.3V or 2.5V compatible, 1:9 clock fanout buffer
targeted for high performance clock tree applications. With output
frequencies up to 350 MHz and output skews less than 150 ps, the device
meets the needs of most demanding clock applications.

Functional Description
MPC9447 is specifically designed to distribute LVCMOS compatible
clock signals up to a frequency of 350 MHz. Each output provides a
precise copy of the input signal with a near zero skew. The outputs buffers
support driving of 50
terminated transmission lines on the incident
edge: each is capable of driving either one parallel terminated or two
series terminated transmission lines.
Two selectable independent LVCMOS compatible clock inputs are available, providing support of redundant clock source
systems. The MPC9447 CLK_STOP control is synchronous to the falling edge of the input clock. It allows the start and stop of the
output clock signal only in a logic low state, thus eliminating potential output runt pulses. Applying the OE control will force the
outputs into high--impedance mode.
All inputs have an internal pull--up or pull--down resistor preventing unused and open inputs from floating. The device supports
a 2.5V or 3.3V power supply and an ambient temperature range of --40
