Integrated Circuit
Horizontal and Vertical Deflection Controller
for Monitors
The NTE7134 is a high performance and efficient solution for autosync monitors in a 32–Lead DIP
type package. The concept is fully DC controllable and can be used in applications with a microcon-
troller and stand–alone in rock bottom solutions.
This device provides synchronization processing, H + V synchronization with full autosync capability,
and very short setting times after mode changes. External power components are givena great deal
of protection. The IC generates the drive waveforms for DC–coupled vertical boosters.
The NTE7134 provides ectended functions e.g. as a flexible SMPS block and an extensive set of ge-
ometry control facilities, providing excellent picture quality.
