General Description

The ICS9248-151 is a single chip clock solution for Desktop

designs. It provides all necessary clock signals for such a

system.

Spread spectrum may be enabled through I

Spread spectrum typically reduces system EMI by 8dB to

10dB. This simplifies EMI qualification without resorting to

board design iterations or costly shielding. The ICS9248-151

employs a proprietary closed loop design, which tightly

controls the percentage of spreading over process and

temperature variations.

Serial programming I

stop clock programming and frequency selection.
