The FS6127 is a monolithic CMOS clock generator IC
designed to minimize cost and component count in digital
video/audio systems.
At the core of the FS6127 is circuitry that implements a
voltage-controlled crystal oscillator when an external
resonator (nominally 13.5MHz) is attached. The VCXO
allows device frequencies to be precisely adjusted for use
in systems that have frequency matching requirements,
such as digital satellite receivers.
A high-resolution phase-locked loop generates the output
clock frequency (CLK). The CLK frequency is phase-
locked and frequency-locked to the VCXO frequency.
