C9851 Datasheet (Cypress Semiconductor)

C9851, Clock Generator

This device provides the necessary clocks for a differential host bus system in multi-processor servers and workstations.

It also generates a 66.6MHz hub clock for interfacing with a complimentary part, the Cypress B9852.

The 2 Mref clock outputs are 180 degrees out of phase and are used for interfa
