(6) The differential output voltage and offset voltage are adjustable through the SPI.
(7) The equalizer automatically shifts equalization stages at cable lengths less than 140 m (Belden 1694A) to reduce power consumption.
This power savings is also achieved by setting Extended 3G Reach Mode = 1 through the SPI.
