On-chip tunable voltage-controlled crystal oscillator
circuitry (VCXO) allows precise system frequency
tuning (pull range typically 300ppm)
VCXO tuning range: 0-3V
Uses inexpensive fundamental-mode crystals
Integrated phase-locked loop (PLL) multiplies VCXO
frequency to the higher system frequencies needed
5V supply voltage (contact factory for 3.3V)
Small circuit board footprint (8-pin 0.150 SOIC)

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.

... Voltage-Controlled Crystal Oscillator (VCXO) The VCXO provides a tunable, low-jitter frequency refer- ence for the rest of the FS6127 system components. Loading capacitance for the crystal is internal to the FS6127. No external components (other than the crystal resonator itself) are required for operation of the VCXO. ...
