Table 6. Serializer CML Driver Strength (Default Level, CMLLVL = 11)
Table 7. Deserializer Cable Equalizer Boost Levels
*Negative preemphasis levels denote deemphasis.
The deserializer includes an adjustable line equalizer to
further compensate cable attenuation at high frequen-
cies. The cable equalizer has 11 selectable levels of
compensation from 2.1dB to 13dB (Table 7). The EQS
input selects the default equalization level at power-up.

Link Serializer/Deserializer
The state of EQS is latched upon power-up or when
resuming from power-down mode. To select other
equalization levels, set the corresponding register bits
in the deserializer (0x05 D[3:0]). Use equalization in the
deserializer, together with preemphasis in the serializer,
to create the most reliable link for a given cable.
