CY2254A - Pentium Processor Compatible Clock Synthesizer/Driver

Datasheet Summary

Description

The CY2254A is a Clock Synthesizer/Driver that provides the multiple clocks required for a Pentium-based PC.

The CY2254A has low-skew outputs (< 250 ps between the CPU Clocks, < 250 ps between the PCI Clocks).

In addition, the CY2254A CPU clock outputs have less than 200 ps cycle-to-cycle jitter.

Features

  • Multiple clock outputs to meet requirements of most Pentium® motherboards.
  • Four pin-selectable CPU clocks @ 66.66 MHz, 60.0 MHz, and 50.0 MHz for support of Intel Triton™ PCIset based PC.
  • 55.0 MHz pin-selectable CPU clock also available (.
  • 2 option only).
  • Six PCI clocks at 1/2 CPU Clock frequency.
  • One I/O clock @ 24 MHz.
  • One Keyboard Controller clock @ 12 MHz (.
  • 1 option) or one Universal Serial Bus clock @ 48 MHz (.
  • 2 o.
