General Description

Four Configurable PLLs

The CY2544, CY2548 and CY2546 have four programmable PLLs that can be used to generate output frequencies ranging from 3 to 166 MHz. The advantage of having four PLLs is that a single device generates up to four independent frequencies from a single crystal.
