The ICS9248-110 is a main clock synthesizer chip for AMD-K7 based systems. This provides all clocks required for such a system when used with a Zero Delay Buffer Chip such as the ICS9179-06.

Spread spectrum of the ICS9248-110 may be enabled through I2C 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 ICS9248-110 employs a proprietary closed loop design, which tightly controls the percentage of spreading over process and  emperature variations.

Serial programming I2C interface allows changing functions, stop clock programming and frequency selection.
