RECEIVE EQUALIZATION
In backplane applications, the AD8153 needs to compensate for
signal degradation caused by long traces. The device supports
two levels of input equalization, configured on a per-port basis.
Table 6 summarizes the high-frequency asymptotic gain boost
for each setting.

TRANSMIT PRE-EMPHASIS
Transmitter pre-emphasis levels can be set by pin control or
through the control registers when using the I2C interface. Pin
control allows two settings of PE. The control registers provide
two additional settings.
