The TDA8303/TDA8303A combines all small signal functions (except the tuner) which are required for a monochrome television receiver. For a complete black and white receiver only the output stages for video, sound, horizontal and vertical deflection and a tuner have to be added.
FEATURES
• Video IF amplifier with synchronous demodulator
• Automatic gain control (AGC) detector suitable for negative modulation
• AGC tuner
• Automatic frequency control (AFC) circuit with sample-and-hold
• Video preamplifier
• Sound IF amplifier and demodulator
• DC volume control or separate supply for starting the horizontal oscillator
• Audio preamplifier
• Horizontal synchronization circuit with two control loops
• Vertical synchronization (divider system) and sawtooth generation with automatic amplitude adjustment for 50 and 60 Hz
• Transmitter identification (mute)
