MK2727
Low Cost 27 MHz VCXO
Description
The MK2727 is MicroClock’s lowest cost, low
jitter, high performance VCXO and PLL clock
synthesizer designed to replace expensive 27MHz
VCXOs. 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 external 13.5 MHz pullable crystal
input to produce a
27 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.
Features
