TBA920 line oscillator combination
DESCRIPTION
The line oscillator combination TBA920 is a monolithic
integrated circuit intended for the horizontal deflection of the black and white
and colour TV sets
picture tube.
FEATURES:
SYNC-PULSE SEPARATION
OPTIONAL NOISE
INVERSION GENERATION OF A LINE FREQUENCY VOL- TAGE BY MEANS OF AN OSCILLATOR PHASE COMPARISON BETWEEN SYNC- PULSE AND THE OSCILLATOR WAVEFORM PHASE COMPARISON BETWEEN THE OS- CILLATOR WAVEFORM AND THE MIDDLE OF THE LINE FLY-BACK PULSE AUTOMATIC SWITCHING OF THE VARIABLE TRANSCONDUCTANCE AND THE VARIABLE TIME CONSTANT TO ACHIEVE NOISE SUP- PRESSION AND, BY SWITCHING OFF, POS- SIBILITY OF TAPE-VIDEO-REGISTERED RE- PRODUCTION SHAPING AND AMPLIFICATION OF THE OS- CILLATOR WAVEFORM TO OBTAIN PULSES FOR THE CONTROL OF DRIVING STAGES IN HORIZONTAL, DEFLECTION CIRCUITS USING EITHER TRANSISTORS OR THYRISTORS.

It includes an 8.8 MHz oscillator and divider, to generate two 4.4 MHz reference signals, and provides color difference output.
The TDA2521 is intended to interface directly with the TDA251O with a minimum of external components and is constructed on a single silicon chip using the Fairchild Planar
epitaxial process.
