DESCRIPTION
The TDA9109A is a monolithic integrated circuit
assembled in a 32-pin shrink dual in line plastic
package. This IC controls all the functions related
to the horizontal and vertical deflection in multi-
mode or multi-frequency computer display moni-
tors.
The internal sync processor, combined with the
very powerful geometry correction block, make
the TDA9109A suitable for very high performance
monitors, using very few external components.
The horizontal jitter level is very low. It is particu-
larly well-suited to high-end 15" and 17" monitors.
Combined with the ST7275 Microcontroller family,
TDA9206 (Video preamplifier) and STV942x (On-
Screen Display controller), the TDA9109A allows
fully I
to be built with a reduced number of external com-
ponents.

... PLL1 is locked, avoiding the horizontal frequency chang- ing too quickly. The dynamic behavior of PLL1 is fixed by an external filter which integrates the cur- rent of the charge pump. A “CRC” filter is generally used (see Figure 7) PLL1F 7 1.8k 10nF 4.7 F TDA9109A A 29/47 ...

... TDA9109A The PLL1 is internally inhibited during extracted vertical sync (if any) to avoid taking in account missing pulses or wrong pulses on phase Figure 8. Figure 9. The VCO uses an external RC network. It delivers a linear sawtooth obtained by the charge and the discharge of the capacitor, with a current propor- tional to the current in the resistor. The typical thresholds of the sawtooth are 1 ...

... The TDA9109A also includes a Lock/Unlock iden- tification block which senses in real time whether PLL1 is locked or not on the incoming horizontal sync signal.

... 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 TDA9109A has the “geometry tracking” feature which allows generation of a dis- symetric parabola depending on the vertical posi- tion. ...

Therefore it is necessary to invert the control signal. – For a N-channel MOS, a transformer is needed to control the gate.
