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.

... Decoupling Capacitors Decoupling capacitors of 0.01µF should be connected between VDD and GND on pins 3 and 6, on pins 5 and 6, and on pins 13 and 14, as close to the MK3732-07 as possible. For optimum device performance, the decoupling capacitors should be mounted on the component side of the PCB. Avoid the use of vias in the decoupling circuit. ...
