TDA5950X Overview
Key Features
- 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 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 5950X is suitable for application in television receivers or video tape recorders with A/V switches
- 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
