ICS9250-28 Datasheet (Integrated Circuit Systems) - Frequency Generator & Integrated Buffers

ICS9250-28, Frequency Generator & Integrated Buffers

The ICS9250-28 is part of a two chip clock solution for 810/810E and 815 type chipset.

Combined with the ICS9112-17, the ICS9250-28 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.
