Output Characteristics
The output characteristics of the SCAN15MB200 have been
optimized for point-to-point backplane and cable applica-
tions, and are not intended for multipoint or multidrop signal-
ing.
A 100
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.

Note 5:
Same functionality for channel 1
Note 6:
When all enable inputs from both channels are Low, the device
enters a powerdown mode. Refer to the applications section titled TRI-STATE
and Powerdown modes.
