DESCRIPTION
The TDA8214B is an horizontal and vertical deflec-
tion 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.

Notes :
1. Width of vertical blanking pulse on SSC output is proportional to the frame flyback time, the switching level is VCC2 - 2VBE and
the other input of the comparator is tied to the frame amplifier output. Application circuit uses the frame flyback generator.
2. An RC network is connected to this input. Typical value for the resistor is 27kand 220pF for the capacitor. A different time
constant for RC changes the delay between the middle of the line synchro pulse and the leading edge of the burst key pulse but
also the duration of the burst key pulse.

To frame amplifier
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 VCC2-2VBE, the pulse is
detected. The line flyback detection is provided by
a comparator which compares the input line flyback
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 2µs sampling
pulse. This 2µs pulse is positionned 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 2VPP (typ. : 2.5VPP).
