CY2273A Datasheet (Cypress Semiconductor) - K6 Clock Synthesizer/Driver

CY2273A, K6 Clock Synthesizer/Driver

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.

There are seven PCI clocks, running at 30
