DESCRIPTION
The STV9211 is an I
2
C Bus controlled RGB pre-
amplifier designed for Monitor applications, able to
mix the RGB signals coming from any OSD device.
The usual Contrast, Brightness, Drive and Cut-Off
(InfraBlack) Controls are provided.
In addition, it includes the following features:
- High resolution cut-off (InfraBlack) adjustment,
- OSD contrast,
- Bandwidth and stand-by control,
- Brightness before/after Drive Selection.
The RGB incoming signals are amplified and
shaped to drive in DC coupling the video amplifier
without intermediate follower stages.
One of the main advantages of ST devices is their
ability to sink and source currents.
These driving capabilities combined with an original
output stage structure suppress any static current
on the output pins and therefore reduce
dramatically the power dissipation of the device.
Extensive integration combined with high
performance and advanced features make the
STV9211 one of the best choice for any CRT
monitor.
Perfectly matched with the ST video amplifiers
STV95xx, they offer a complete solution for high
performance and cost-optimized Video Board
Application.
