Benefits
Inventory of only one device, CY22800, is needed in various
applications such as HDTV, STB, DVDR, etc.
Multiple predefined configurations that can be programmed
into a single chip
Eliminates the need for expensive and difficult to use
higher-order crystal
High-performance PLL tailored for multiple applications
Meets critical timing requirements in complex system
designs
Enables application compatibility
Allows up to three different frequency selects
