MK2703
PLL Audio Clock Synthesizer
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 our 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.
MicroClock manufactures the largest variety of
Set-Top Box and multimedia clock synthesizers
for all applications. Consult MicroClock to
eliminate VCXOs, crystals and oscillators from
your board.
Features
⢠Packaged in 8 pin SOIC
⢠Uses an inexpensive fundamental crystal, or clock
⢠Supports MPEG sampling rates of 32 kHz,
44.1 kHz, 48 kHz and 96 kHz
⢠Patented zero ppm synthesis error in all clocks
⢠All frequencies are frequency locked
⢠25 mA output drive capability at TTL levels
⢠Advanced, low power, sub-micron CMOS process
⢠3.3 V or 5 V operating voltage
⢠For audio clocks that require lower jitter, use the
MK2731-03C
⢠Industrial temperature version available
