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 SEIC
x 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_SRDS
n (xcorevss).
