General Description

The ICS9250-08 is the single chip clock solution for Desktop/

designs using BX, Appollo Pro 133 type of chip sets. It provides

all necessary clock signals for such a system.

Spread spectrum typically reduces system EMI by 8dB to

10dB. This simplifies EMI qualification without resorting to

board design iterations or costly shielding. The ICS9250-08

employs a proprietary closed loop design, which tightly

controls the percentage of spreading over process and

temperature variations.

stop clock programming and frequency selection.
