Philips Semiconductors
I²C-bus autosync deflection controller for
PC monitors
Product specification
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.
