Datasheet
MDS 2731-04 CA
The MK2731-04 is a low cost, low jitter, high
performance clock synthesizer designed to replace
expensive discrete clock oscillators in MPEG audio
applications. Using ICS/MicroClock’s patented
analog/digital Phase-Locked Loop (PLL)
techniques, the device uses an inexpensive
14.4 MHz crystal input to produce all of the
popular audio sampling frequencies.
ICS manufactures the largest variety of Set-Top
Box and multimedia clock synthesizers for all
applications. Consult ICS to eliminate VCXOs,
crystals and oscillators from your board.
