Enhanced Three-Speed Ethernet Controller (eTSEC)
(10/100/1000 Mbps)—MII/RGMII Electrical Characteristics
The electrical characteristics specified here apply to all the media independent interface (MII) and reduced
gigabit media independent interface (RGMII), signals except management data input/output (MDIO) and
management data clock (MDC). The RGMII interface is defined for 2.5 V, while the MII interface can be
operated at 3.3 V. The RGMII interface follows the Hewlett-Packard reduced pin-count interface for
Gigabit Ethernet Physical Layer Device Specification Version 1.2a (9/22/2000). The electrical
characteristics for MDIO and MDC are specified in Section 8.3, “Ethernet Management Interface
8.1.1
eTSEC DC Electrical Characteristics
All MII and RGMII drivers and receivers comply with the DC parametric attributes specified in Table 21
and Table 22. The RGMII signals are based on a 2.5-V CMOS interface voltage as defined by JEDEC
EIA/JESD8-5.
