2.0 Description
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 (VCXO) 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.
