... The X-Ray protection is activated by application of a high level on the X-Ray input (more than 8.2V on Pin 25). It inhibits the H-Drive and B+ outputs from 30 % This activation is internally delayed by 2 lines to avoid erratic detection when short parasitics are present . TDA9111 - around FLY H . ...

I C (see Figure page 28). 2.6 Horizontal and Vertical Dynamic Focus For dynamic focus adjustment, the TDA9111 de- livers the sum of two signals on pin 10: – a parabolic waveform at horizontal frequency, – a parabolic waveform at vertical frequency. The horizontal parabola comes from a sawtooth in phase advance with flyback pulse middle. The Figure 14 ...

... REF-V ly centered on 3.6V. By changing the vertical posi- tion, the sawtooth shifts by 0.4V. To provide good screen geometry for any end user adjustment, the TDA9111 has the “geometry tracking” feature which automatically adapts the parabola shape, depending on the vertical position and size. ...

Page 32

... TDA9111 Due to the large output stage voltage range (E/W Pin Cushion, Keystone, E/W Corner), the combi- nation of the tracking function, maximum vertical amplitude, maximum or minimum vertical position and maximum gain on the DAC control may lead to output stage saturation. This must be avoided by limiting the output voltage with appro- ...
