MK2703 Datasheet, PDF (1/7 Pages) Integrated Circuit Systems – PLL Audio Clock Synthesizer

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.
