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.
