I²C-bus autosync deflection controllers for
PC/TV monitors
Product specification
TDA4853; TDA4854
GENERAL DESCRIPTION
The TDA4854 is a high performance and efficient solution
for autosync monitors. All functions are controllable by
I²C-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 I²C-bus driven Philips TDA488x video
processor family, a very advanced system solution is
offered.
