DESCRIPTION
The TDA8213 is a monolithic integrated circuit in
DIP20 package for colourand black & white television receivers using PNP tuners. It is intendedto
operate with a negativelymodulated vision carrier
and frequencymodulated soundcarrier.Used with
TDA8214/15 (H/Vdeflection circuit)and TDA8217
(Pal decoderand videoprocessor), this IC permits
a completelow-cost solution for PALapplications.
