Product Summary

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. The 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 of MPC9447 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.
