IDT, Integrated Device Technology Inc MK2772-01S

Description
The MK2772-01 is a low-cost, low-jitter, high-performance VCXO and clock synthesizer designed for set-top boxes. It utilizes an on-chip Voltage Controlled Crystal Oscillator (VCXO) that accepts a 0 to 3V input voltage to adjust the output clocks by ±100 ppm. Employing ICS's patented VCXO and analog Phase-Locked Loop (PLL) techniques, the device generates multiple output clocks from an inexpensive 13.5 MHz crystal input. All clocks are frequency-locked to the 27.00 MHz output (and to each other) with zero ppm error. The MK2772-01 features a glitch-free multiplexer for seamless switching between input sources during operation.
