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.
All clocks are frequency locked to the 27.
00MHz output (and to each other) with zero ppm error.
The MK2772 includes a glitch-free multiplexer to switch input sources during operation.
MicroClock manufactures the largest variety of Set-Top Box and multimedia clock synthe...
