DATASHEET

MK2703

Description

The MK2703 is a low-cost, low-jitter, high-performance PLL

clock synthesizer designed to replace oscillators and PLL

circuits in set-top box and multimedia systems. Using IDT’s

patented analog Phase Locked Loop (PLL) techniques, the

device uses a 27 MHz crystal or clock input to produce a

buffered reference clock and a selectable audio clock.

IDT manufactures the largest variety of Set-Top Box and

multimedia clock synthesizers for all applications. Consult

IDT to eliminate VCXOs, crystals and oscillators from your

board.
