This IC controls all the functions related to horizontal and vertical deflection in multimode or multi-frequency puter display monitors. The internal sync processor, bined with the powerful geometry correction block, makes the STV6888 suitable for very high performance monitors, using few external ponents. bined with other ST ponents dedicated for CRT monitors (microcontroller, video preamplifier, video amplifier, OSD controller) the STV6888 allows fully I2C bus-controlled puter display monitors to be built with a reduced number of external ponents ORDERING INFORMATION Vertical section s 200 Hz maximum frequency s Vertical ramp for DC-coupled output...
