Pre-emphasis
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 to preset values per the Pre-
emphasis Control Selection Table.
Output Characteristics
The output characteristics of the SCAN90CP02 device have
been optimized for point-to-point backplane and cable appli-
cations.
