The SAA5030 is a monolithic bipolar integrated circuit used for Teletext video processing. It is one of a package of four circuits to be used in Teletext TV data systems. The SAA5030 extracts data and data clock information from the television composite video signal and feeds this to the Acquisition and Control Circuit SAA5040. A 6MHz crystal-controlled, phase-locked oscillator is incorporated which derives the Timing Chain Circuit SAA5020. An adaptive sync separator is also provided which derives line and field sync pulses from the input video to synchronize the timing chain.
