The FS6209 is a monolithic CMOS clock generator IC
designed to minimize cost and component count in digital
video/audio systems.
At the core of the FS6209 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.
Two high-resolution phase-locked loops generate two
output clocks (CLKA and CLKB) through an array of post-
dividers. All frequencies are ratiometrically derived from
the VCXO frequency. The locking of all the output fre-
quencies together 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 FS6209 system components. Loading capacitance for the crystal is internal to the FS6209. No external components (other than the reso- nator itself) are required for operation of the VCXO. ...
