The TDA4854 is a high performance and efficient solution for autosync monitors. All functions are
controllable by IC-bus.
The TDA4854 provides synchronization processing, horizontal and vertical synchronization with full
autosync capability, a TV/VCR mode 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 TDA4854 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.
The TDA4853 is an economy version of the TDA4854, especially designed for use in 14" and 15"
monitors with combined EHT generation. It provides the same features as the TDA4854 except for the
dynamic focus block.
Together with the IC-bus driven Philips TDA488x video processor family, a very advanced system
solution is offered.
