General Description

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.

I C R O C LOC K.

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.
All clocks are frequency locked. All will vary the same amount (in ppm) as the VCXO.
Selectable Audio clock for 256x, 384x, and 512x.
