TDA8120B - Multistandard Video And Sound if System

General Description

The TDA8120B is a monolithic IC for TV video IF and Sound IF amplification and demodulation that can operate with all the TV standards.

The Video IF section can handle negative (B/G) or positive (L) modulated video signals by means of DC switching.

GAIN CONTROLLED IF AMPLIFIER VIF OPERATING FREQUENCY UP TO 50MHz SYNCHRONOUS DETECTOR WHITE SPOT INVERTER VERY LOW DIFFERENTIAL ERROR VERY LOW PHASE ERROR INTERNAL AGC SWITCH (B/G - L) AGC TOP. SYNCH. FOR STANDARD B/G AGC TOP WHITE FOR STANDARD L QUASI SPLIT SOUND FOR STANDARD B/G SOUND DETECTOR FOR STANDARD L VIDEO MUTING FACILITY SEPARATED SOUND OUTPUT OPERATES WITHOUT EXTERNAL GATING PULSE The Sound IF section acts as a Quasi Split Sound (QSS) subsystem in B/G transmission and allows a second Sound IF with high rejection of the video information. The DC switch can modify the Sound IF configuration to process AM modulated Sound signals (L).
