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.
