2.9.1

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).

The electrical characteristics for MDIO and MDC are specified in Section 2.10, “Ethernet Management Interface Electrical

Characteristics.”

The electrical characteristics for SGMII is specified in Section 2.9.3, “SGMII Interface Electrical Characteristics.” The SGMII

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.
