DESCRIPTION
The TDA8219 is a monolithic integrated color de-
coder for the PAL/NTSC standard. It includes in a
20 pins IC all the functions required for the identifi-
cation and demodulationof PAL/NTSCsignals, 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.
