VCXO PLUS AUDIO CLOCK FOR STB
MK3722
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.
