Output Characteristics
The output characteristics of the DS15MB200 have been
optimized for point-to-point backplane and cable applica-
tions, and are not intended for multipoint or multidrop signal-
ing.
A 100Ω output (source) termination resistor is incorporated
in the device to eliminate the need for an external resistor,
providing excellent drive characteristics by locating the
source termination as close to the output as physically pos-
sible.
Pre-Emphasis Controls
The pre-emphasis is used to compensate for long or lossy
transmission media. Separate pins are provided for each
output to minimize power consumption. Pre-emphasis is
programmable to be off or on per the Pre-emphasis Control
Table.
