GENERAL DESCRIPTION
The TDA8215B performs all the video and power
functions required to provide signals for the line
driver and frame yoke.
It contains:
- A synchronization separator
- An integrated frame separator without external
components
- A saw-tooth generator for the frame
- A power amplifier for direct drive of frame yoke
(short circuit protected)
- An open collector output for the line darlington
drive
- A line phase detector and a voltage control oscil-
lator
- A super sandcastle generator
- Video identification output.
The slice level of sync-separation is fixed by value
of the external resistors R1 and R2. VR is an
internally fixed voltage.
The sync-pulse allows the discharge of the capaci-
tor by a 2 x I current. A line sync-pulse is not able
to discharge the capacitor under VZ/2. A frame
sync-pulse permits the complete discharge of the
capacitor, so during the frame sync-pulse Q3 and
Q4 provide current for the other parts of the circuit.
