DESCRIPTION
The STV8211is a monolithic integrated circuit in
DIP20 package for black& whitetelevision receivers usingPNP tuners. It is intendedtooperatewith
a negatively modulated vision carrier and frequency modulated sound carrier. Used with
TEA2037A(H/V deflectioncircuit), this IC permits
a complete low-cost solution for black and white
applications.
