The FS6128 is a monolithic CMOS clock generator IC
designed to minimize cost and component count in digital
video/audio systems.
At the core of the FS6128 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 an output
clock (CLK) through a post-divider. The CLK frequency is
ratiometrically derived from the VCXO frequency. The
locking of the CLK frequency to other system reference
frequencies can eliminate unpredictable artifacts in video
systems and reduce electromagnetic interference (EMI)
due to frequency harmonic stacking.

... Voltage-Controlled Crystal Oscillator (VCXO) The VCXO provides a tunable, low-jitter frequency refer- ence for the rest of the FS6128 system components. Loading capacitance for the crystal is internal to the FS6128. No external components (other than the reso- nator itself) are required for operation of the VCXO. ...
