MK2771-15
REV F 032204
Description
The MK2771-15 is a low-cost, low-jitter, high-performance
VCXO and clock synthesizer designed for set-top boxes.
The on-chip Voltage Controlled Crystal Oscillator accepts a
0 to 3 V input voltage to cause the output clocks to vary by
±100 ppm. Using ICS’ patented VCXO and analog
Phase-Locked Loop (PLL) techniques, the device uses an
inexpensive 13.5 MHz pullable crystal input to produce
multiple output clocks including two selectable processor
clocks, a selectable audio clock, two communications
clocks, and three fixed clocks. All clocks are frequency
locked to the 27.00 MHz output (and to each other) with zero
ppm error, so any output can be used as the VCXO output.
Features
