Ethernet: Enhanced Three-Speed Ethernet (eTSEC)
clock is not required for this port. Instead, SerDes reference clock is required on L1_SD_REF_CLK and
L1_SD_REF_CLK pins.

Enhanced Three-Speed Ethernet Controller (eTSEC)
(10/100/1000 Mbps)—SGMII/MII/RGMII/RTBI/RMII DC Electrical
Characteristics
The electrical characteristics specified here apply to serial gigabit media independent interface (SGMII),
media independent interface (MII), reduced gigabit media independent interface (RGMII), reduced ten-bit
interface (RTBI), reduced media independent interface (RMII) signals, management data input/output
(MDIO) and management data clock (MDC).
The MII and RMII interfaces are defined for 3.3 V, while the RGMII and RTBI interfaces can be operated
at 2.5 V. The SGMII interface conforms to the Serial-GMII Specification Version 1.8 with some
exceptions. The RGMII and RTBI interfaces follow the Reduced Gigabit Media-Independent Interface
(RGMII) Specification Version 1.3. The RMII interface follows the RMII Consortium RMII Specification
Version 1.2.
