TV-Stereo Processor

Preliminary Data

Semiconductor Group

Type

TDA 6812-2M

TDA 6812-2 is a complete system for stereo TV-sound, controlled by an I

made up of three functional blocks.

1. Stereo Processing with High Quality (better than DIN 45500; suitable for NICAM and CD

2. TV-Identification-Signal Decoder

Features

a) Matrix for G-standard with I

b) Three stereo AF-inputs

c) Random switching of all inputs to all outputs

d) Stereo SCART-interface

e) Stereo loudspeaker signal section with volume precontrol, treble/bass control, enlargement of

f) Stereo headphones signal section with Ch1/Ch2 and volume control

a) Active pilot-tone filter

b) Phase-independent rectifier with very narrow bandwidth for identification-signal decoding

c) Digital integrator for noise rejection

d) Multiplexer for cyclic scanning for stereo or dual-sound identification

e) Externally synchronized PLL for reference-signal generation: synchronization with line sync
