TDA5930-5

Video IF Amplifier and Demodulator TDA 5930-5 Bipolar IC Features q q q q Multistandard video IF Interference suppression circuitry Mean/peak value control Area of application: multistandard TV / VCR, mono, stereo cable converter, mono, stereo P-DIP-16-1 Type TDA 5930-5 Ordering Code Q67000-A5135 Package P-DIP-16-1 Circuit Description Video IF for all European standards. The analog setting function (delayed tuner AGC threshold) is controlled via a potentiometer. The IC is suitable for use in Euro- or multi-standard TV sets for mono and stereo application. The component includes a four-stage, capacitively coupled, symmetrically designed and controlled amplifier, a limiter with selection, and a mixer for quasi-synchronous demodulation of positive and negative modulated IF signals. In addition a video output amplifier and noise suppression circuitry are included. This output is used for generating the AGC voltage. The AGC for both modulation types has been realized as integral AGC with noise-free peak and mean value detector (only for positive modulation). A delayed tuner AGC with positive AGC direction (increase in tuner AGC voltage → increased gain) is derived from the AGC voltage via a threshold amplifier set by means of an external potentiometer. A positive video output with 3 Vpp and a negative video output with 2 Vpp are available.
