System Design Information
The following pins must be connected to XGND_SRDS2:
The POR configuration pin cfg_srds_sgmii_en on UART_RTS[1] can be used to power down SerDes 2
block for power saving. Note that both SVDD_SRDS2 and XVDD_SRDS2 must remain powered.
21.10.4 SerDes 2 Interface (SGMII) Partly Unused
If only part of the high speed SerDes 2 interface (SGMII) 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):
The following pins must be connected to XGND_SRDS2:
