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 IDT’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.
