LNB Supply Low Voltage
Low voltage = Vlow_nom + VLOW[3:0] x 0.0625V + Vboost, where
Vlow_nom is determined by the LNBLVL(CEh[1]) register bit, and
Vboost is determined by the COMP(CEh[2]) register bit.
Default: 8h resulting in low voltage = Vlow_nom + 0.5 V + Vboost.
LNB Supply High Voltage
High voltage = Vhigh_nom + VHIGH[3:0] x 0.0625V + Vboost, where
Vhigh_nom is determined by the LNBLVL(CEh[1]) register bit, and
Vboost is determined by the COMP(CEh[2]) register bit.
Default: 8h resulting in High voltage = Vhigh_nom + 0.5 V + Vboost.
