ICS950703 - Programmable Timing Control Hub

Datasheet Summary

Description

The ICS950703 is a single chip clock solution for desktop designs using the Intel Brookdale chipset with Rambus RDRAM memory.

It provides all necessary clock signals for such a system.

The ICS950703 is part of a whole new line of ICS clock generators and buffers called TCH™ (Timing Control Hub).

Features

  • 4 Differential CPU Clock Pairs @ 3.3V.
  • 2 - 3V MREF clocks for memory reference seeds, (separate single ended but 180 degrees out of phase).
  • 4 - 66MHz 3V66 output.
  • 10 - 3V 33MHz PCI clocks.
  • 2 - 48MHz clocks (180 degrees out of phase).
  • 2 - 14.318 reference output (180 degrees out of phase) Key Specifications:.
  • 3V66 Output jitter.
