ICS9250-10, Frequency Timing Generator

The ICS9250-10 is a single chip clock for Intel Pentium II.

It provides all necessary clock signals for such a system.

Spread spectrum may be enabled through I2C programming.

Spread spectrum typically reduces EMI by 8dB to 10 dB.

This simplifies EMI qualification without resorting to board design it
