RGMII/ULPI Interface
The Zynq Ult MPSoC SOM supports RGMII or ULPI interface on Board to Board Connector1. In Zynq
Ult MPSoC PS, GEM3 RGMII interface and USB1 ULPI interface are multiplexed on the same pins. So either
one interface only can be used at a time. In Zynq Ult MPSoC SOM, these MIO pins are directly connected
from MPSoC to Board to Board conenctor1. If RGMII/ULPI interface is not required on these pins, the same pins can
be used as GPIOs or other alternate functions. Please refer PS Min Multiplexing section
functions.
The Zynq Ult MPSoC gigabit Ethernet controller (GEM) implements a 10/100/1000 Mb/s Ethernet MAC that
is compatible with the IEEE Standard for Ethernet (IEEE Std 802.3-2008). GEM controller supports MDIO interface for
external PHY Management and it can be used through any PL Bank IOs through EMIO interface in SOM.
