I2C GEOMETRY CORRECTIONS VERTICAL PARABOLA GENERATOR (Pin Cushion - E/W, Keystone, Corner) HORIZONTAL DYNAMIC PHASE (Side Pin Balance & Parallelogram) VERTICAL DYNAMIC FOCUS (Vertical Focus Amplitude) COMPARED WITH THE TDA9109, 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 CONVERTER. DESCRIPTION The TDA9109/S is a monolithic integrated circuit assembled in 32-pin shrink dual in line plastic package. 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" monit...
