DESCRIPTION
The TDA9109/S is a monolithic integrated circuit
assembled in 32-pin shrink dual in line plastic pack-
age. This IC controls all the functions related to the
horizontal and vertical deflection in multimode or
multi-frequency computer display monitors.
The internal sync processor, combined with the very
powerful geometry correction block make the
TDA9109/S suitable for very high performance
monitors, using very few external components.
The horizontal jitter level is very low. It is particularly
well suited for high-end 15" and 17" monitors.
Combined with the ST7275 Microcontroller fam-
ily, TDA9206 (Video preamplifier) and STV942x
(On-Screen Display controller) the TDA9109/S
allows fully I
.
monitors to be built with a reduced number of
external components.
COMPARED
THE TDA9109/S HAS :
- CORNER CORRECTION,
- HORIZONTAL MOIRÉ,
- B+ SOFT START,
- INCREASED MAX. VERTICAL FREQUENCY,
- NO HORIZONTAL FOCUS,
- NO STEP DOWN OPTION FOR DC/DC CON-
VERTER.

... TDA9109/S OPERATING DESCRIPTION (continued) II.2 - PLL1 The PLL1 consists of a phase comparator, an exter- nal filter and a voltage-controlled oscillator (VCO). The phase comparator is a "phase frequency" type designed in CMOS technology. This kind of phase detector avoids locking on wrong frequencies followed by a "charge pump", composed of two current sources : sunk and sourced (typically I = 1mA when locked and I = 140 A when unlocked) ...

... REF and HSYNC /10 phase adjustment is possible. H The TDA9109/S 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. The resulting information is available on HLOCKOUT (see Sync Processor). ...

... The VOUT sawtooth is typically centered on 3.5V. By changing the vertical position, the sawtooth shifts by 0.3V. In order to have good screen geometry for any end user adjustment, the TDA9109/S has the "geome- try tracking" feature, which allows generation of a dissymetric parabola depending on the vertical position. ...
