The MAX9511 is a complete solution to interface a
video graphics controller to a VGA port and/or docking
station with optimal video performance and minimal
electromagnetic interference (EMI) emission. The
MAX9511 has output drivers with variable EMI suppres-
sion for graphics video and sync (RGBHV) signals. The
MAX9511 includes external load-detection circuitry.
The MAX9511 suppresses EMI emissions by limiting
the slew rate (SR) rather than limiting bandwidth with
fixed L-C filters. The SR controls the large-signal band-
width without affecting the small-signal bandwidth,
resulting in sharper video images, while reducing EMI.
The SR of the MAX9511 provides tighter control than
traditional passive L-C components, and allows the SR
to track the resolution by varying an external resistor
(R
The load-detection circuitry of the MAX9511 automatically
detects and transmits a change in load status to the input
stages when an external load (monitor, docking station, or
projector) is connected. The MAX9511 is compatible with
the load-detection circuitry on the digital-to-analog (DAC)
outputs of most video graphics controllers. The output
drivers provide 6dB of gain to compensate for the 75Ω
back-termination resistors, which reduce transmission line
reflections.
The RGBHV channels can be placed into shutdown to
reduce power when no external load is connected.
The MAX9511 operates from 3V and 5V supplies. The
DDC circuitry performs bidirectional level translation
from 3V to 5V logic levels. The MAX9511 is offered in a
24-pin QSOP package and is specified over the com-
mercial 0°C to +70°C temperature range.
