DESCRIPTION The TDA8219 is a monolithic integrated color decoder for the PAL / NTSC standard. It includes in a 20 pins IC all the functions required for the identification and demodulation of PAL / NTSC signals, and all the videoprocessor functions up to the drive of the video stages. Used with TDA8213 (video & sound IF system) and TDA8214B (H / V deflection circuit), this IC permits a complete low-cost solution for PAL / NTSC applications. PIN CONNECTIONS
