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.
