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 configura-

tion to process AM modulated Sound signals (L).

The TDA8120B isassembled in a 24 pin dual inline

power package.

DESCRIPTION

DIP24

The TDA8120B is a monolithic IC for TV video IF

and Sound IF amplification and demodulationthat

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.
