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.
