Functional Description
The CY22800 is a multi-function 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 marketplace. The CY22800 is
a field-programmable synthesizer that can be programmed using
an easy-to-use programmer dongle, CY36800, with one of many
predefined configuration files for fast sample generation of
prototype builds. The CY22800 is a reprogrammable device that
can be programmed up to 100 times. The latest configurations
available for this device are summarized in CY22800
Configurations on page 5.
