CY2280 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. The CY2280 can be used with the CY231x for a total solution for systems with SDRAM.
