General Description

Two Configurable PLLs

The CY25402, CY25422, and CY25482 have two programmable PLLs that can be used to generate output frequencies ranging from 3 to 166 MHz. The advantage of having two PLLs is that a single device generates two independent frequencies from a single crystal.

Dear valued customer,
