CLOCK
The MK2744 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
fundamental mode crystal or clock input to
produce multiple output clocks including the
processor clock, 27MHz, 3.6864MHz, and a
selectable audio clock. The audio clocks are
exactly frequency locked to the 27.00MHz input
with zero ppm error, allowing audio and video to
track exactly, thereby eliminating the need for
large buffer memory.
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.
