Notes:

1. This does l not align to DC-coupled SGMII.

2. |VOD| = |VSD_TXn – VSD_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 XMITEQAB (for SerDes lanes

0 & 1) or XMITEQEF (for SerDes lanes 2 & 3) bit field of the MPC8569E SerDes control register:

• The MSB (bit 0) of the above bit field is set to zero (selecting the full VDD-DIFF-p-p amplitude—power up default);

• The LSB (bit [1:3]) of the above bit field is set based on the equalization setting shown in table.

4. The |VOD| value shown in the Typ column is based on the condition of XVDD-Typ = 1.0V and 1.1 V, no common mode offset

variation, SerDes transmitter is terminated with 100-

Ω differential load between SD_TX[n] and SD_TX[n].
