VCXO Plus Audio Clock For STBThe 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 IDTs 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
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.
