The MK2751 is a low cost, low jitter, high
performance clock synthesizer designed for
MPEG and Set-top box systems. 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 divide by two of the
processor clock, the audio processor or
NTSC/PAL 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
Works well with C-Cube MPEG decoders and
AuraVision video processors
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
and 30 or 33.0MHz
Zero ppm error in audio clocks give highest
performance audio tracking with video
25mA output drive capability at TTL levels
Advanced, low power, sub-micron CMOS process
5V±10% operating voltage
(external capacitors
needed for crystal input)
