General Description
The ICS9248-165 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 ICS9248-165
employs a proprietary closed loop design, which tightly
controls the percentage of spreading over process and
temperature variations.
