00
Equalizer Status Valid
These bits informs the user about the current state of the receive
equalization network. Only valid if LIM1.EQON is set.
00 = Equalizer status not valid, still adapting
01 = Equalizer status valid
10 = Equalizer status not valid
11 = Equalizer status valid but high noise floor
Receive Equalizer Status
The current line attenuation status in steps of about 1.7 dB are
displayed in these bits. Only valid if bits EV(1:0) = 01 and
LIM1.EQON = 1. Accuracy: ± 2 digits, based on temperature
influence and noise amplitude variations.
00000 = Minimum attenuation: 0 dB
...
11001 = Maximum attenuation: -43 dB
