DESCRIPTION

The TDA8219 is a monolithic integrated color de­coder for the PAL/NTSC standard.It includes in a
20 pinsIC all the functions required for theidentifi­cationanddemodulationofPAL/NTSCsignals,and
all the videoprocessor functions up to the drive of
the video stages. Used with TDA8213 (video
& sound IFsystem)andTDA8214B(H/Vdeflection
circuit),thisICpermitsacompletelow-costsolution
for PAL/NTSCapplications.
