GMAC SERDES & SGMII Interface Usage (Host/
Network)
This section discusses the use of GMAC interfaces for both the network and host side
interfaces n0, n1, h0, h1 when configured to support operation in SERDES or SGMII modes.
The signal SERDES_RREF (ball number U10) is used to set the nominal drive current for the
SERDES output. This signal should be connected through a 1K-1% ohm resistor to VDDS
(1.0V).
For applications that use the SERDES/SGMII interface instead of the GMII/TBI interface,
the control pins and clock pins for the unused interface may be connected through pull-
down or pull-up resistors. Unused bus input pins may be terminated with pull-up or pull-
down resistors. Unused bus output pins may be left unconnected.
