VCXO Plus Audio Clock For STB

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 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. Packaged in 16-pin TSSOP Available in Pb (lead) free package Replaces a VCXO and Oscillator Operating voltage of 3.3 V Provides output of 27 MHz plus Audio Clock Uses an inexpensive 27 MHz pullable crystal On-chip patented VCXO with pull range of 230 ppm (minimum) VCXO tuning voltage of 0 to 3.3 V Advanced, low power, sub-micron CMOS process By Integrated Device Technology
