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.

• Pin and Function Compatible to MPC947

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 50W 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_C to +85_C. The MPC9447 is pin and function compatible

but performance–enhanced to the MPC947.
