Description

The TDA4841PS is a high performance and efficient solution for autosync monitors. All functions are controllable by the I2C-bus.

The TDA4841PS 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 TDA486x and TDA835x.

The TDA4841PS 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.
