VIDEO & SOUND IF SYSTEM
DESCRIPTION
The TDA8213 is a monolithic integrated circuit in
DIP20 package for colour and black & white televi-
sion receivers using PNP tuners. It is intended to
operate with a negatively modulated vision carrier
and frequency modulated sound carrier. Used with
TDA8214/15 (H/V deflection circuit) and TDA8217
(Pal decoder and video processor), this IC permits
a complete low-cost solution for PAL applications.
