CLOCK
The MK2742 is a low cost, low jitter, high
performance clock synthesizer for MPEG I,
MPEG II, and set-top box based applications.
Using analog Phase-Locked Loop (PLL)
techniques, the device accepts a 27.00MHz crystal
or clock input to produce multiple output clocks
including the processor clock, 27MHz, 13.5MHz,
3.6864MHz, and a selectable audio clock. The
audio clocks (on the -03 and -04) and the
13.5MHz, 27MHz and 3.68MHz clocks are
exactly frequency locked to the 27.00MHz input
with zero ppm error, allowing audio and video to
track exactly.
MicroClock manufactures the largest variety of
Set-Top Box and multimedia clock synthesizers
for all applications. Consult MicroClock to
eliminate crystals and oscillators from your board.
