Motorola MPC9447
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. Each output provides a precise copy of the input signal with a near zero skew.| Part No. | MPC9447 |

APPLICATIONS
● Pin and Function Compatible to MPC947 FunctionalDESCRIPTION
MPC9447 is specifically designed to distribute LVCMOS compatible clock signals up to a frequency of 350 MHz. The outputs buffers support driving of 50Ω 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.
