Overview

MOTOROLA SEMICONDUCTOR TECHNICAL DATA Advance Information Multiple Output Clock Synthesizer The MPC9108 is a multiple CMOS output clock synthesizer targeted for disk drive applications.

The device interfaces to a 20MHz crystal as its frequency source.

From this source the device provides a buffered copy of the 20MHz clock as well as synthesized 40MHz and 50MHz output clocks.
