PL603-27
DESCRIPTION
Phase Link’s PL603-27 is a clock generator IC, specifically designed to acmodate the clock requirements of the set top box, HDTV, and personal video recording (PVR) receiver equipment. It offers seven different clock signals while utilizing a single low-cost 27MHz crystal input. Phase Link’s PL603-27 is designed to save board space and implementation cost while producing multiple system clock outputs.
