Figure 2-13 to Figure 2-15 shows the VoD of the TDP1204 while operating in linear mode. Although, there is no voltage swing difference between VoD settings for linear mode the VoD is higher than the VoD of the limited redriver mode.

Note, the link training pattern 4 (LTP4) is the waveform used in this section for ease of examining the VoD.

Figure 2-16 to Figure 2-18 shows that in limited mode the differential output swing increases as the VoD setting in the VoD register increases in value. The VoD increases more going from VoD = 0 setting to VoD = 7 setting then it does for VoD = 0 to VoD = 3.

Table 2-3 summarizes the performance of the TDP1204 when modifying the swing voltage between linear and limited redriver modes.
