General Description
The ICS9248-141 is a main clock synthesizer chip for AMD-K7 based systems with VIA style chipset. This provides all clocks
required for such a system.
Spread spectrum may be enabled through I
This simplifies EMI qualification without resorting to board design iterations or costly shielding. The ICS9248-141
employs a proprietary closed loop design, which tightly controls the percentage of spreading over process and temperature
variations.
