Description

The CY2287PVC-1T is an IC chip that belongs to the category of electronic components. Specifically, it is a part of the CY2280 series, which is a spread spectrum clock synthesizer and driver designed for use in Pentium II or similar processor-based PCs that require 100-MHz support. The CY2287PVC-1T is a space-saving 48-pin SSOP package that provides all the necessary system clocks for such devices. It can also be paired with the CY231x to form a complete solution for systems with SDRAM.
