ICS9248-101
Frequency Generator & Integrated Buffers for PENTIUM/ProTM & K6
General Description
The ICS9248-101 is the single chip clock solution for Notebook designs using the 440BX or the VIA Apollo Pro 133 style chipset. It provides all necessary clock signals for such a system. Spread spectrum 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 ICS9248-101 employs a proprietary closed loop design, which tightly controls the percentage of spreading over process and temperature variations.
