Enhanced Three-Speed Ethernet Controller (eTSEC)
(10/100/1000 Mbps) — FIFO/GMII/MII/TBI/RGMII/RTBI/RMII Electrical
Characteristics
The electrical characteristics specified here apply to all FIFO mode, gigabit media independent interface (GMII), media
independent interface (MII), ten-bit interface (TBI), reduced gigabit media independent interface (RGMII), reduced ten-bit
interface (RTBI), and reduced media independent interface (RMII) signals except management data input/output (MDIO) and
management data clock (MDC), and serial gigabit media independent interface (SGMII). The RGMII, RTBI and FIFO mode
interfaces are defined for 2.5 V, while the GMII, MII, RMII, and TBI interfaces can operate at 3.3V.
The GMII, MII, or TBI interface timing is compliant with IEEE 802.3. The RGMII and RTBI interfaces follow the Reduced
Gigabit Media-Independent Interface (RGMII) Specification Version 1.3 (12/10/2000). The RMII interface follows the RMII
Consortium RMII Specification Version 1.2 (3/20/1998).
interface conforms (with exceptions) to the Serial-GMII Specification Version 1.8.
2.9.1.1
GMII, MII, TBI, RGMII, RMII and RTBI DC Electrical Characteristics
All GMII, MII, TBI, RGMII, RMII and RTBI drivers and receivers comply with the DC parametric attributes specified in
Table 24 and
Table 25. The RGMII and RTBI signals are based on a 2.5-V CMOS interface voltage as defined by JEDEC
EIA/JESD8-5.
