TDA9110
LOW-COST DEFLECTION PROCESSOR FOR MULTISYNC MONITORS
PRODUCT PR EVIEW
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 F ocus 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 f or 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.
