General Description

The ICS9250-18 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 may be enabled through I

2C programming. Spread spectrum typically reduces system EMI by 8dB to

10dB. This simplifies EMI qualification without resorting to board design iterations or costly shielding. The ICS9250-18

employs a proprietary closed loop design, which tightly controls the percentage of spreading over process and temperature

variations.

Serial programming I

2C interface allows changing functions, stop clock programming and frequency selection.
