Hello,

Could you please let me know the detail of adaptive equalizer?
In the datasheet page 43, there is equalization register which include EQ stage 1 and 2 select.

I understood that these values are wrote automatically.
However, I think that we can write these register for adjust EQ value.
Please let me know meaning of these value.

Asaka-san,

An user can read only the register data, not a dB value for example.

Hello Sugiura san,

Please allow me changing my question.
According to the datasheet, EQ in DS90UB926 supports up to 10m STP cable loss.
I think the cable loss depends on the cable quality (other wards insertion loss)
Can you let me know how much insertion loss, is the 10 m STP cable assumed?
