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 13.5 MHz) 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.
