Guidelines for High-Speed Interface Termination
The following pins must be connected to XGND if not used:
3.11.3
If the high-speed SerDes 2 interface (SGMII/ SATA) is not used at all, the unused pin should be terminated as described in this
section. See SerDes2 in
The following pins must be left unconnected (float):
The following pins must be connected to X2GND:
The POR configuration pin cfg_srds2_prtcl[0:2] on TSEC1_TXD[2], TSEC3_TXD[2], TSEC_1588_PUSLE_OUT1 can be
used to power down SerDes 2 block for power saving. Note that both S2VDD and X2VDD must remain powered.
3.11.4
If only part of the high speed SerDes 2 (SGMII/SATA) interface pins are used, the remaining high-speed serial I/O pins should
be terminated as described in this section.
The following pins must be left unconnected (float) if not used:
The following pins must be connected to X2GND if not used:
