ICS9250-22

General Description

Pin Configuration

The ICS9250-22 is a single chip clock solution.

Spread spectrum typically reduces system EMI by 8dB to 10dB. This simplifies EMI qualification without resorting to

board design iterations or costly shielding. The ICS9250-22 employs a proprietary closed loop design, which tightly

controls the percentage of spreading over process and temperature variations.
