----------------------------------------------------------------- Functional Description, Application
Video IF Section Video IF broadband amplifier followed by a quasi-synchronous demodulator for negative modulated IF signals. A video switch 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 video switch. The tuner AGC threshold is set by means of a potentiometer, all other functions can be switched with open collector transistors.
Sound IF Section FM IF limiter with FM PLL demodulator for the frequency range of 5.5 MHz to 6.5 MHz. The AF section includes an audio switch followed by an audio buffer output.
Application The TDA 5950 is suitable for application in television receivers or video tape recorders with A / V switches.

IC-SPECIFICATION
----------------------------------------------------------------- Circuit Description
Video IF Section The video IF section incorporates a four-stage, capacitively coupled, symmetrical and controlled amplifier, a limiter with selection and a mixer for quasi-synchronous demodulation of negative modulated IF signals followed by a video output amplifier. The video demodulator output and the video switch input are connected by means of a sound trap. The video switch has two inputs (for signals from video demodulator and from external source) and two outputs. Parallel to the video output amplifier the video signal is used for generating the AGC voltage. The control circuit is designed on the integralaction AGC principle, employing a noise-free peak value detector. A delayed tuner AGC voltage with positive control direction is derived from the AGC voltage via a threshold amplifier that is set by means of an external potentiometer. An AFC push pull output current is generated from picture carrier tank circuit.
Sound IF Section The sound IF section incorporates a five-stage, symmetrical limiter amplifier followed by a PLL demodulator. The AF section contains an audio switch followed by an output buffer.

Alignment Instructions At a video carrier input level of V23/24 = 4 mVrms, fPC = 38,9 MHz, and a superimposed AGC voltage of V3 = 1,5 V, the demodulator tank cicuit is preliminarily aligned until a max. video signal V14pp is obtained at the video output. Any suitable video test signal can be used for modulation. The AGC voltage V3 is reduced until the signal is approx. 1 Vpp and the max. videosignal is obtained when fine-aligning the demodulator tank circuit. The alignment is not critical due to relatively large bandwidth of the demodulator tank circuit. Fine-tuning to intercarrier S/N, differential phase or 2T pulse characteristics is possible.
