LOW COST VCXO
MK2731-01
Description
The MK2731-01 is a low cost, low jitter,
high-performance VCXO and PLL clock synthesizer
designed to replace expensive discrete VCXOs, PLLs
and oscillators. 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 ICS’s
patented VCXO and analog Phase-Locked Loop (PLL)
techniques, the device uses an inexpensive 10 MHz or
13.5 MHz pullable crystal input to produce two low
skew output clocks.
ICS manufactures a large variety of Set-Top Box and
multimedia clock synthesizers for all applications. If
more clock outputs are needed, see the MK277x family
of parts. Consult ICS to eliminate VCXOs, crystals and
oscillators from your board.
