General Description

Configurable PLLs

The CY25403/CY25423/CY25483 have three programmable PLLs that can be used to generate output frequencies ranging from 3 to 166 MHz. The advantage of having three PLLs is that a single device generates up to three independent frequencies from a single crystal.
