General Description
The CY22801 is a flash-programmable clock generator that
supports various applications in consumer and communications
markets. The device uses the Cypress-proprietary PLL along
with Spread Spectrum and VCXO technology to make it one of
the most versatile clock synthesizers in the market. The device
uses a Cypress-proprietary PLL to drive up to three configurable
outputs in an 8-pin SOIC.
The CY22801 is programmed with an easy-to-use programmer
dongle, the CY36800, in conjunction with the CyClocksRT™
software. This enables fast sample generation of prototype
builds for user-defined frequencies.
