ICS9250-27 Datasheet (Integrated Circuit Systems) - Frequency Generator & Integrated Buffers

ICS9250-27, Frequency Generator & Integrated Buffers

The ICS9250-27 is a single chip clock solution for 810/810E and 815 type chipset.

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 resort
