Ethernet Interface
This section provides the AC and DC electrical characteristics for the Ethernet interfaces inside the QUICC Engine block.
2.6.1
GMII/SGMII/MII/SMII/RMII/TBI/RGMII/RTBI Electrical Characteristics
The electrical characteristics specified here apply to all gigabit media independent interface (GMII), serial gigabit media
independent interface (SGMII), 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 and TBI interfaces are defined for 3.3 V. The GMII, MII, and TBI interface timing is compatible with
IEEE Std 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 the SGMII is specified in Section 2.6.4, “SGMII Interface Electrical
Characteristics.” The electrical characteristics for MDIO and MDC are specified in Section 2.7, “Ethernet Management
2.6.2
GMII, MII, RMII, SMII, TBI, RGMII and RTBI DC Electrical
Characteristics
The following table shows the GMII, MII, RMII, SMII, and TBI DC electrical characteristics when operating from a 3.3 V
supply.
The following table shows the RGMII, and RTBI DC electrical characteristics when operating from a 2.5 V supply.
