DESCRIPTION

The TDA8214B is an horizontal and vertical deflec­tion circuit with super sandcastle generator and
video identification output. Used with TDA8213
(Video & Sound IF system) and TDA8217 (Pal
decoder and video processor), this IC permits a
complete low-cost solution for PAL applications .
