The FS6011-02 is a monolithic CMOS clock generator IC
designed to minimize cost and component count in digital
video/audio systems.
At the core of the FS6011-02 is circuitry that implements
a voltage-controlled crystal oscillator when an external
resonator (nominally 27MHz) is attached. The VCXO al-
lows device frequencies to be precisely adjusted for use
in systems that have frequency matching requirements,
such as digital satellite receivers.
Three high-resolution phase-locked loops independently
generate three other selectable frequencies derived from
the VCXO frequency. These clock frequencies are re-
lated to the VCXO frequency and to each other by exact
ratios. The locking of all the output frequencies together
can eliminate unpredictable artifacts in video systems
and unpredictable electromagnetic interference (EMI)
performance due to frequency harmonic stacking.
