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. Cypress’s value-added distribution partners and third-party programming systems from BP Microsystems, HiLo Systems, and others, can also be contacted for large production quantities. A JEDEC file needs to be configured to program CY22801, which can be generated using the CyClocksRT™ software.
