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 CyClocksRTâ¢
software. This enables fast sample generation of prototype
builds for user-defined frequencies. Cypressâs 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.
