CY2254A Datasheet and Specifications PDF

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.

* 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 frequenc.
