MK2704
Synthesizer
Description
The MK2704 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 fundamental 27 MHz crystal or clock
input to produce a buffered reference clock and a
selectable audio clock. The audio clock is
frequency locked to the 27 MHz clock, assuring
that the audio with zero ppm error and video will
always track perfectly.
Features
• Packaged in 8 pin SOIC
• Uses an inexpensive fundamental crystal, or clock
• Output clocks of 16.9344 MHz, 18.432 MHz,
and 36.864 MHz
• Supports 384x MPEG sampling rates of 44.1 kHz,
48 kHz and 96 kHz
• Patented zero ppm synthesis error in all clocks
• All frequencies are frequency locked
• Advanced, low power, sub-micron CMOS process
• 3.3 V or 5 V operating voltage
