MK3732-07
ADSL VCXO CLOCK SOURCE
Description
The MK3732-07 is a low cost, low jitter, high
performance VCXO and PLL clock synthesizer
designed to replace expensive VCXO modules and
oscillators. The on-chip Voltage Controlled Crystal
Oscillator (VCXO) accepts a 0 to 3.3 V input voltage to
cause the output clocks to vary by +100 ppm. Using
ICS’ patented VCXO and analog Phase-Locked Loop
(PLL) techniques, the device uses an inexpensive
13.248 MHz pullable crystal input to produce one or
two output clocks.
The MK3732-07 is a pin-to-pin replacement for the
MK2732-07 when using +3.3V supply voltage.
ICS manufactures the largest variety of xDSL clock
synthesizers for all applications. Consult ICS to
eliminate VCXOs, crystals, and oscillators from your
board.
