Block Diagram
The MK2754 is MicroClock’s lowest cost, low
jitter, high performance VCXO and PLL clock
synthesizer designed to replace expensive 54 MHz
VCXOs. The on-chip Voltage Controlled Crystal
Oscillator accepts a 0 to 3V input voltage to vary
the output clocks by ±100 ppm. Using
MicroClock’s patented VCXO and analog Phase-
Locked Loop (PLL) techniques, the device uses an
inexpensive external 13.5 MHz pullable crystal
input to produce a 54 MHz output clock.
MicroClock manufactures the largest variety of
Set-Top Box and multimedia clock synthesizers
for all applications. If more clock outputs are
needed, see the MK2731 or MK277x family of
parts. Consult MicroClock to eliminate VCXOs,
crystals and oscillators from your board.
