VCXO PLUS AUDIO CLOCK FOR STB
IDT™ 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 IDT’s 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.
IDT manufactures the largest variety of VCXO based timing
devices for all applications. Consult IDT 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.
