VCXO PLUS AUDIO CLOCK FOR STB
IDT™ / ICS™ VCXO PLUS AUDIO CLOCK FOR STB
Description
The MK3722 is a low cost, low jitter, high performance
VCXO and PLL clock synthesizer designed to replace
expensive discrete VCXOs and multipliers. The patented
on-chip Voltage Controlled Crystal Oscillator accepts a 0 to
3.3 V input voltage to cause the output clocks to vary by
±115 ppm. Using ICS’ analog/digital Phase-Locked Loop
(PLL) techniques, the device uses an inexpensive 27 MHz
pullable crystal input to produce a reference output and a
selectable audio clock.
ICS manufactures the largest variety of VCXO based timing
devices for all applications. Consult ICS to eliminate
VCXOs, crystals, and oscillators from your board.
The frequency of the on-chip VCXO is adjusted by an
external control voltage connected to VIN. Because VIN is
a high impedance input, it can be driven directly from an
PWM RC integrator circuit.

... Decoupling Capacitors Decoupling capacitors of 0.01µF should be connected between VDD and GND on pins 3 and 4, pins 6 and 7, and pins 11 and 14 as close to the MK3722 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. ...
