CY2280 - 100-MHz Pentium II Clock Synthesizer/Driver with Spread Spectrum for Mobile or Desktop PCs

Description

The CY2280 is a Spread Spectrum clock synthesizer/driver for a Pentium II, or other similar processor-based PC requiring 100-MHz support.

All of the required system clocks are provided in a space-saving 48-pin SSOP package.

Features

  • Mixed 2.5V and 3.3V operation.
  • Clock solution for Pentium® II, and other similar processor-based motherboards.
  • Four 2.5V CPU clocks up to 100 MHz.
  • Eight 3.3V sync. PCI clocks, one free-running.
  • Two 3.3V 48-MHz USB clocks.
  • Three 3.3V Ref. clocks at 14.318 MHz.
  • Two 2.5V APIC clocks at 14.318 MHz or PCI/2.
  • EMI control.
  • Spread spectrum clocking.
  • Factory-EPROM programmable spread spectrum margin.
  • Facto.
