... TDA4471 Circuit Description Vision IF amplifier The video IF signal (VIF) is fed through a SAW filter to one of the two VIF inputs (Pins 6–7 or 10–11). The selection of VIF input is controlled by Pin 16 in combina- tion with the standard switch. With a minimal external expense it is possible to switch between two different SAW filters. Both VIF inputs features excellent cross– ...
