1. Slice level (referred to RXDIN) is calculated as follows: VSLICE = (SLICE_LVL – 0.4 VREF)/15.
2. Sample Phase Offset is calculated as follows: PHASE OFFSET = 22.5 (PHASEADJ – 0.4 VREF)/0.3
3. LOS Threshold voltage (referred to RXDIN) is calculated as follows: VLOS = 30 mV + (LOS_LVL – 0.4 VREF)/15.
