DESCRIPTION
The TDA8217 is a monolithic integrated color de-
coder for the PAL standard. It includes in a 20 pins
IC all the functions required for the identification
and demodulationof PAL signals, and all the video-
processor functions up to the drive of the video
stages. Used with TDA8213 (video & sound IF
system) and TDA8214A(H/V deflection circuit), this
IC permits a complete low-cost solution for PAL
applications.
