1.3.4 System Frequency Synthesizer SecretandDocumentDDR-SDRAM Buffer: ICS950403

The ICS950403 is a system clock synthesizerMiTacchip for AMD K8 based notebook systems with AMD, VIA or Ali

chipset. This provides all clocks required for such system. The ICS950403 employs a proprietary closed loop

design, which tightly controlsConfidentialthe percentage of spre ding over process and temperature variations. Serial ￿ 8 - PCICLK (Including 1 free running) @ 3.3 V

programming I 2 C interface allows changi g functions, stop clock programming and frequency selection.

￿ 2 - Differential pair push-pull CPU clocks @ 3.3V

￿ 3 - Selectable PCICLK/HTTCLK @ 3.3V ￿ 1 - HTTCLK @ 3.3V

￿ 1 - 48MHz @ 3.3V fixed
