CY2273A - K6 Clock Synthesizer/Driver

Description

The CY2273A is a clock synthesizer/driver for a Pentium, Pentium II, Cyrix, or AMD processor-based PC using Intel’s 82430TX, 82440LX, ALI Aladdin IV or Aladdin IV+ chipsets.

The CY2273A-1 outputs four CPU clocks at 2.5V or 3.3V with up to 83.3MHz operation.

Features

  • Mixed 2.5V and 3.3V operation.
  • Complete clock solution for Pentium®, Pentium® II, Cyrix, and AMD processor-based motherboards.
  • Four CPU clocks at 2.5V or 3.3V.
  • Up to twelve 3.3V SDRAM clocks.
  • Seven synchronous PCI clocks, one free-running.
  • One 3.3V 48 MHz USB clock.
  • One 2.5V IOAPIC clock (-3 option only).
  • Two AGP clocks at 60 or 66.6MHz (-2 option only).
  • One 3.3V Ref. clock at 14.318 MHz.
  • I2C™ Serial Confi.
