PL603-27
PRODUCT DESCRIPTION
PhaseLink’s PL603-27 is a clock generator IC, specifically designed to accommodate 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. PhaseLink’s PL603-27 is designed to save board
space and implementation cost while producing multiple system clock outputs.
