3 / 56 page  1999 Jul 13 3 Philips Semiconductors Product specification I2C-bus autosync deflection controller for PC monitors TDA4856 GENERAL DESCRIPTION The TDA4856 is a high performance and efficient solution for autosync monitors. All functions are controllable by the I2C-bus. The TDA4856 provides synchronization processing, horizontal and vertical synchronization with full autosync capability and very short settling times after mode changes. External power components are given a great deal of protection. The IC generates the drive waveforms for DC-coupled vertical boosters such as the TDA486x and TDA835x. The TDA4856 provides extended functions e.g. as a flexible B+ control, an extensive set of geometry control facilities, and a combined output for horizontal and vertical focus signals. Together with the I2C-bus driven Philips TDA488x video processor family, a very advanced system solution is offered. QUICK REFERENCE DATA ORDERING INFORMATION SYMBOL PARAMETER MIN. TYP. MAX.
