Description
Features
The MK2771-05 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 14.31818 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.
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 14.31818 MHz crystal
On-chip patented VCXO with pull range
of 200ppm (typical)
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
