The MK3732-08 is a low cost, low jitter, high
performance VCXO and PLL clock synthesizer
designed to replace expensive discrete VCXOs and
multipliers. 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/MicroClock’s patented VCXO and analog/digital
Phase-Locked Loop (PLL) techniques, the device
uses an inexpensive 17.664 MHz or 24.576 MHz
pullable crystal input to produce one or two output
clocks.
ICS manufactures the largest variety of xDSL clock
synthesizers for all applications. Consult ICS to
eliminate VCXOs, crystals and oscillators from your
board.

... VI = Analog Voltage Input; XI Crystal Pins. External Components The MK3732-08 requires a minimum number of external components for proper operation. Decoupling capacitors of 0.01µF should be connected between VDD and GND pins 3 and 7, pins 4 and 8, and pins 5 and 9, as close to the MK3732-08 as possible. A series termination resistor of 33 must be connected as close to the chip as possible ...
