This section provides the AC and DC electrical characteristics for three-speed, 10/100/1000, and MII
management.
8.1
The electrical characteristics specified here apply to all GMII (gigabit media independent interface), the
MII (media independent interface), TBI (ten-bit interface), RGMII (reduced gigabit media independent
interface), and RTBI (reduced ten-bit interface) signals except MDIO (management data input/output) and
MDC (management data clock). The RGMII and RTBI interfaces are defined for 2.5 V, while the GMII
and TBI interfaces can be operated at 3.3 V or 2.5 V. Whether the GMII, MII, or TBI interface is operated
at 3.3 or 2.5 V, the timing is compliant with the IEEE 802.3 standard. The RGMII and RTBI interfaces
follow 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 Electrical
8.1.1
All GMII, MII, TBI, RGMII, and RTBI drivers and receivers comply with the DC parametric attributes
specified in
RTBI receiver may exceed the potential of the receiver’s power supply (for example, a GMII driver
powered from a 3.6-V supply driving V
for dissimilar GMII driver and receiver supply potentials is implicit in these specifications. The RGMII
and RTBI signals are based on a 2.5-V CMOS interface voltage as defined by JEDEC EIA/JESD8-5.
