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
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 ICS9248-
151
employs a proprietary closed loop design, which tightly
controls the percentage of spreading over process and
temperature variations.
