1. This does not align to DC-coupled SGMII.
2. │VOD│ = │VSD_TXn_P - VSD_TXn_N│. │VOD│ is also referred to as output differential peak voltage. VTX-DIFFp-p = 2 x │VOD│.
3. The │VOD│ value shown in the Typ column is based on the condition of XVDD_SRDSn-Typ = 1.35 V, no common mode
offset variation. SerDes transmitter is terminated with 100-Ω differential load between SDn_TXn_P and SDn_TXn_N.
4. For recommended operating conditions, see Table 3.
This figure shows an example of a 4-wire AC-coupled SGMII serial link connection.
