The TDA8218 performs all the video and power
functions required to provide signals for the line
driver and frameyoke.
It contains:
A synchronizationseparator
An integrated frame separator without external
components
Figure1
: SynchronizationSeparatorCircuit
A saw-tooth generator for the frame
A power amplifier for direct drive of frame yoke
(short circuitprotected)
An opencollector outputfor the line driver
A line phase detector and a voltage control os-
cillator
A super sandcastlegenerator.

The slice level of sync-separationis fixed by value of the external resistors R1 and R2. V
R
is an internally
fixed voltage.
The sync-pulseallows the dischargeof thecapaci-
tor by a 2 x I current. Aline sync-pulse is not able
to discharge the capacitor under V

sync-pulse permits the complete discharge of the
