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.

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
oscillator
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 inter-
nally fixed voltage.
The sync-pulse allows the discharge of the capac-
itor by a 2 x I current. A line sync-pulse is not able
to discharge the capacitor under V
Z
/2. A frame
sync-pulse permits the complete discharge of the
capacitor, so during the frame sync-pulse Q
3
and
Q
4
provide current for the other parts of the circuit.

Figure 6. Line Oscillator
The oscillator thresholds are internally fixed by re-
sistors. The discharge of the capacitor depends on
the internal resistor R4. The control voltage is ap-
plied on resistor R5. The sync-pulse drives the
current in the comparator. The line flyback inte-
grated by the external net work gives on pin 13 a
saw tooth, the DC offset of this saw tooth is fixed
by VC. The comparator output provides a positive
current for the part of the signal on pin 13 greater
than to VC and a negative current for the other
part.When the line flyback and the video signal are
synchronized, the output of the comparator is an
alternatively negative and positive current. The
frame sync-pulse inhibits the comparator to pre-
vent frequency drift of the line oscillator on the
frame beginning.

Figure 8.
Line output (Pin 17)
It is an open-collector output. The output negative
pulse time is 22s for a 64s period.
The oscillator thresholds are internally fixed by re-
sistors. The oscillator is synchronized during the
last half free run period. The input current during
the charge of the capacitor is less than 100nA.
Figure 9. Frame Oscillator
Frame output amplifier
This amplifier is able to drive directly the frame
yoke. Its output is short circuit and overload pro-
tected; it contains also a thermal protection.
The frame blanking is detected by the frame fly-
back generator. When the output voltage of the
frame amplifier exceeds V
CC2
-2V
BE
, the pulse is
detected. The line flyback detection is provided by
a comparator which compares the input line fly-
back pulse to an internal reference. The burst gate
pulse position is fixed by the external RC network
(Pin 14). It is referenced to the middle of the line
flyback.
This stage will detect the coincidence between the
line sync pulse (if present) and a 2s sampling
pulse. This 2s pulse is positioned at the center of
line sync pulse when the phase loop is locked.
This sampled detection is stored by an external
capacitor Pin 8.
The identification output level is high when video
signal is present.
Important remark: minimum saw-tooth amplitude
on Pin 13 has to be 2V

(typ.: 2.5V

).
