This section provides the AC and DC electrical characteristics for the enhanced three-speed Ethernet
controller.
8.1
The electrical characteristics specified here apply to 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 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.
8.1.1
MII and RMII drivers and receivers comply with the DC parametric attributes specified in
Table
defined by JEDEC EIA/JESD8-5.
