TDA9110

TDA9110 LOW-COST DEFLECTION PROCESSOR FOR MULTISYNC MONITORS PRODUCT PREVIEW I C GEOMETRY CORRECTIONS VERTICAL PARABOLA GENERATOR (Pincushion, Keystone) HORIZONTAL SIZE CONTROL (Amplitude) HORIZONTAL DYNAMIC PHASE (Side Pin Balance & Parallelogram) HORIZONTAL AND VERTICAL DYNAMIC FOCUS (Horizontal Focus Amplitude, Horizontal Focus Symmetry, Vertical Focus Amplitude) GENERAL SYNCHRO PROCESSOR 12V SUPPLY VOLTAGE 8V REFERENCE VOLTAGE HOR. & VERT. LOCK UNLOCK OUTPUTS READ/WRITE I 2C INTERFACE HORIZONTAL AND VERTICAL MOIRE DESCRIPTION The TDA9110 is a monolithic integrated circuit assembled in 32-pin shrunk 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 synchro processor, combined with the very powerful geometry correction block make the TDA9110 suitable for very high performance monitors with very few external components. The horizontal jitter level is extremely low. (Typical standard deviation : 300ps @ 31kHz). It is particularly well suited for high-end 15” and 17” monitors.
