DESCRIPTION
The TDA9106 is a monolithic integrated circuit as-
sembled in 42 pins shrunk dual in line plastic pack-
age. This IC controls all the functions related to the
horizontal and vertical deflection in multimodes or
multi-frequency computer display monitors.
The internal sync processor, combined with the very
powerful geometry correction block are making the
TDA9106 suitable for very high performance moni-
tors with very few external components.
It is particularly well suited for high-end 15” and 17”
monitors.
