STMicroelectronics TDA9111

The TDA9111 is a monolithic integrated circuit assembled in a 32-pin shrink dual-in-line plastic package. This IC controls all the functions related to horizontal and vertical deflection in multimode or multi-frequency computer display monitors. The internal sync processor, combined with the powerful geometry correction block, makes the TDA9111 suitable for very high performance monitors, using few external components.

DESCRIPTION

The horizontal jitter level is very low. It is particularly well-suited to high-end 15” and 17” monitors. Combined with the ST7275 Microcontroller family, TDA9206 (Video preamplifier) and STV942x (OnScreen Display controller), the TDA9111 allows fully-I2C bus-controlled computer display monitors to be built with a reduced number of external components. Self-adaptative Dual PLL concept s 150kHz maximum frequency s X-Ray protection input 2 s I C controls: Horizontal duty-cycle, H-position, horizontal si...
