Functional Description and Application
Video IF Section
Video IF-broadband amplifier followed by a quasi-synchronous demodulator for negative
modulated IF signals. A Full-SCART interface is included in the video section. A separate video
output after the demodulator permits the installation of one or more sound traps at the input of the
SCART switch. The tuner AGC threshold is set by means of a potentiometer, all other functions can
switched with open collector transistors.
Sound IF Section
FM-IF limiter with FM-PLL demodulator. The AF section has a Full-SCART switch followed by a
volume control. The volume is controlled by an analog voltage.
Application
The TDA 5940-2 is suitable for application in television receivers with Full-SCART.
