Note:
1. Slice level (referred to RXDIN) is calculated as follows: VSLICE = (SLICE_LVL – 0.4
VREF)/15.
2. Sample Phase Offset is calcul ated as follows: PHASE OFFSET = 45° (PHASEADJ – 0.4
VREF)/0.3
3. LOS Threshold voltage (r eferred to RXDIN) is calculated as follows: VLOS = 30mV + (LOS_LVL – 0.4
VREF)/15.
