VCXO and HDTV Set-Top Clock Source
Description
The MK3771-17 is a low cost, low jitter,
high-perfomance VCXO and clock synthesizer
designed for set-top boxes and HDTV receivers. The
on-chip Voltage Controlled Crystal Oscillator accepts a
0 to 3.3 V input voltage to cause the output clocks to
vary by ±100 ppm. Using ICS’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 including selectable
BCLK, a selectable audio clock, two communications
clocks, a 13.5 MHz clock, and three 27 MHz clocks. All
clocks are frequency locked to the 27 MHz output (and
to each other) with zero ppm error, so any output can
be used as the VCXO output.
