Enhanced Three-Speed Ethernet (eTSEC)
This section provides the AC and DC electrical characteristics for the enhanced three-speed Ethernet
controller. The electrical characteristics for MDIO and MDC are specified in Section 9, “Ethernet
Management Interface Electrical Characteristics.”
8.1
Enhanced Three-Speed Ethernet Controller (eTSEC)
(10/100/1Gb Mbps)—GMII/MII/TBI/RGMII/RTBI/RMII Electrical
Characteristics
The electrical characteristics specified here apply to all 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). The RGMII and RTBI
interfaces are defined for 2.5 V, while the GMII, MII, and TBI interfaces can be operated at 3.3 or 2.5 V.
The GMII, MII, or TBI interface timing is compliant with the 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). The electrical characteristics for MDIO and MDC are specified in Section 9, “Ethernet
Management Interface Electrical Characteristics.”
8.1.1
eTSEC DC Electrical Characteristics
All GMII, MII, TBI, RGMII, RMII, and RTBI drivers and receivers comply with the DC parametric
attributes specified in Table 22 and Table 23. The RGMII and RTBI signals are based on a 2.5-V CMOS
interface voltage as defined by JEDEC EIA/JESD8-5.
