MK2772-01 Overview
The MK2772-01 is a low cost, low jitter, high performance VCXO and clock synthesizer for settop boxes. The on-chip Voltage Controlled Crystal Oscillator accepts a 0 to 3V input voltage to cause the output clocks to vary by ±100 ppm. Using MicroClock’s patented VCXO and analog Phase-Locked Loop (PLL) techniques, the device uses an inexpensive 13.5 MHz crystal input to produce multiple output clocks.
MK2772-01 Key Features
- Packaged in 20 pin SOIC
- Uses an inexpensive 13.5 MHz crystal
- On-chip VCXO (patented) with pull range of 200ppm (minimum)
- Ability to switch input sources “on-the-fly”
- VCXO tuning voltage of 0 to 3V
- Zero ppm synthesis error (patented) in all clocks. All exactly track 27MHz VCXO
