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.

MULTIPLE OUTPUT CLOCK SYNTHESIZER
• Low cost, low jitter design • Low cost 8–lead SOIC packaging
In addition to the output clock frequencies, the MPC9108 also offers a lock indicator output. When the internal PLL achieves phase and frequency lock the CLK_LOCK signal will go HIGH.
