W210 - Spread Spectrum FTG for VIA K7 Chipset

Datasheet Summary

Description

CPU Clock Output 0: CPUT0 and CPUC0 are the differential CPU clock outputs for the K7 processor.

CPUT_CS is the open-drain clock output for the chipset.

It has the same phase relationship as CPUT0.

Features

  • Maximized EMI Suppression using Cypress’s Spread Spectrum technology.
  • Single-chip system frequency synthesizer for VIA K7 chipset.
  • One pair of differential CPU outputs for K7 Processor.
  • One open-drain CPU output for VIA K7 chipset.
  • Six copies of PCI output.
  • One 48-MHz output for USB.
  • One 24-MHz or 48-MHz output for SIO.
  • Two buffered reference outputs.
  • Thirteen SDRAM outputs provide support for 3 DIMMs.
  • Sup.
