Overview

PLL AUDIO CLOCK SYNTHESIZER 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.
