The MK2743 is a low cost, low jitter, high
performance clock synthesizer designed for
C-Cube MPEG encoders. 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, low skew divides by two and four of the
processor clock, the audio processor clock, 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.
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.
Packaged in 16 pin narrow (150 mil) SOIC
For C-Cube MPEG encoders
Selectable audio sampling frequencies support
32 kHz, 44.1 kHz, and 48 kHz in most DACs
27.00 MHz crystal or clock input
Selectable processor frequencies of 60 or 66.0MHz
Zero ppm error in audio clocks give highest
performance audio encoding
25mA output drive capability at TTL levels
Advanced, low power, sub-micron CMOS process
5V±10% operating voltage
(external capacitors
needed for crystal input)
