General Description

The ICS9248-150 is a main clock for ServerWorks Grand Champion Systems.

Spread spectrum typically reduces system EMI by 8dB to 10dB. This simplifies EMI qualification without resorting to board design iterations or costly shielding. The ICS9248-150 employs a proprietary closed loop design, which tightly controls the percentage of spreading over process and temperature variations.
