Notes:
1. This will not align to DC-coupled SGMII. XVDD_SRDS-Typ =1.0 V.
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 SRDSnCR0[DDPA] and
SRDSnCR0[TXEQA] for lane A, and SRDSnCR0[DDPE] and SRDSnCR0[TXEQE] for lane E.
4. DPPA or DPPE bit is set to zero (selecting the full VDD-DIFF-p-p amplitude – power up default);
5. TXEQA or TXDQE is set based on the equalization setting shown in table.
6. VOS is also referred to as output common mode voltage.
7. The |VOD| value shown in the Typ column is based on the condition of XVDD_SRDS-Typ = 1.0 V, no common mode offset
variation (VOS = 500 mV), SerDes1 transmitter is terminated with 100- differential load between SD_TXn and SD_TXn.

Notes:
1. Input must be externally AC-coupled.
2. VRX_DIFFp-p is also referred to as peak to peak input differential voltage.
3. The concept of this parameter is equivalent to the Electrical Idle Detect Threshold parameter in PCI Express. Refer to PCI
Express Differential Receiver (RX) Input Specifications section for further explanation.
4. The SEICx shown in the table refers to SRDSnCR[SEICA] for lane A and SRDSnCR[SEICE] for lane E.
5. VCM_ACp-p is also referred to as peak to peak AC common mode voltage.
6. On-chip termination to SGND_SRDSn (xcorevss).
