I2C-bus autosync deflection controller for
PC monitors
Product specification
TDA4841PS
GENERAL 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.
