Notes:
1. This will not align to DC-coupled SGMII.
2. |VOD| = |VSD2_TXn – VSD2_TXn|. |VOD| is also referred as output differential peak voltage. VTX-DIFFp-p = 2*|VOD|.
3. The |VOD| value shown in the table assumes the following transmit equalization setting in the XMITEQCD (for SerDes 2 lane
2 and 3) bit field of MPC8544E SerDes 2 control register 1:
The MSbit (bit 0) of the above bit field is set to zero (selecting the full VDD-DIFF-p-p amplitude—power up default);
The LSbits (bit [1:3]) of the above bit field is set based on the equalization setting shown in this table.
4. VOS is also referred to as output common mode voltage.
5. The |VOD| value shown in the Typ column is based on the condition of XVDD_SRDS2-Typ = 1.0 V, no common mode offset
variation (VOS = 500 mV), SerDes2 transmitter is terminated with 100-Ωdifferential load between SD2_TX[n] and SD2_TX[n].
