Link Port Low Voltage, Differential-Signal (LVDS)

Electrical Characteristics, and Timing

Table 30 and Table 31 with Figure 16 provide the electrical characteristics for the LVDS link ports. The LVDS link port sig- nal definitions represent all differential signals with a VOD = 0 V level and use signal naming without N (negative) and P (posi- tive) suffixes (see Figure 17).
