Notes:
1. This will not align to DC-coupled SGMII. XCOREVDD-Typ = 1.0 V.
2. |VOD| = |VTXn – VTXn|. |VOD| is also referred as output differential peak voltage. VTX-DIFFp-p = 2*|VOD|.
3. The |VOD| value shown in the Typ column is based on the condition of XCOREVDD-Typ = 1.0 V, no common mode offset
variation (VOS = 500 mV), SerDes transmitter is terminated with 100-Ω differential load between TX[n] and TX[n].
4. VOS is also referred to as output common mode voltage.
