ICS9250-16
The ICS9250-16 is a single chip clock solution for 810/810E 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 resorting to board design iterations or
costly shielding. The ICS9250-16 employs a proprietary closed
loop design, which tightly controls the percentage of spreading
over process and temperature variations.
