Functional Description
The CY22393, CY22394, and CY22395 are a family of parts
designed as upgrades to the existing CY22392 device. These
parts have similar performance to the CY22392, but provide
advanced features to meet the needs of more demanding
applications.
The clock family has three PLLs which, when combined with the
reference, allow up to four independent frequencies to be output
on up to six pins. These three PLLs are completely
programmable.
The CY223931 is the CY22393 with NiPdAu lead finish.
