The MK3771-17 is a low cost, low jitter, high
performance 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 (R verstion) or ±115 (A version). 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 27.00 MHz output (and to each other)
with zero ppm error, so any output can be used as the
VCXO output.
