DESCRIPTION

The TDA8217 is a monolithic integrated color de­coder forthePALstandard. It includesina 20 pins
IC all the functions required for the identification
and demodulationof PALsignals,and allthe video­processor functions up to the drive of the video
stages. Used with TDA8213 (video & sound IF
system)andTDA8214A(H/Vdeflectioncircuit),this
IC permits a complete low-cost solution for PAL
applications.
