Description
Features
The MK2772-01 is a low cost, low jitter, high
performance VCXO and clock synthesizer for set-
top boxes. The on-chip Voltage Controlled
Crystal Oscillator accepts a 0 to 3V input voltage
to cause the output clocks to vary by ±100 ppm.
Using MicroClock’s patented VCXO and analog
Phase-Locked Loop (PLL) techniques, the device
uses an inexpensive 13.5 MHz crystal input to
produce multiple output clocks. All clocks are
frequency locked to the 27.00MHz output (and to
each other) with zero ppm error. The MK2772
includes a glitch-free multiplexer to switch input
sources during operation.
MicroClock manufactures the largest variety of
Set-Top Box and multimedia clock synthesizers
for all applications. Consult MicroClock to
eliminate VCXOs, crystals and oscillators from
your board.
Packaged in 20 pin SOIC
Uses an inexpensive 13.5 MHz crystal
On-chip VCXO (patented) with pull range
of 200ppm (minimum)
Ability to switch input sources “on-the-fly”
VCXO tuning voltage of 0 to 3V
Zero ppm synthesis error (patented) in all
clocks. All exactly track 27MHz VCXO
All clocks are frequency locked. All will vary the
same amount (in ppm) as the VCXO
Selectable Audio clock for 256x, 384x, and 512x.
