DESCRIPTION
The TDA8215B is an horizontal and vertical de-
flection 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. The TDA8215B has been specially
designed for direct drive of line DARLINGTON
transistors.
