I2C-bus autosync deﬂection controller for

PC monitors

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.
