4.5 Multiplexed Ball Connections
4.5.1 GMII/RGMII/SerDes/OMI Multiplexed Ball Connections
Table 16 lists the balls used for the line-side interfaces (GMII, RGMII, SerDes/OMI) and provides
a guide to connect these balls. Some of these balls are multiplexed depending on the mode of
operation selected for that port.
Note: Do not connect any balls marked as unused (NC).

1. An external pull-up resistor is required with most optical modules.
2. An open drain I/O, external 4.7 k Ω pull-up resistor is required.
