Ethernet: Three-Speed Ethernet, MII Management
This section provides the AC and DC electrical characteristics for three-speeds (10/100/1000 Mbps) and
MII management.
8.1
Three-Speed Ethernet Controller (TSEC)— MII/RGMII/RTBI
Electrical Characteristics
The electrical characteristics specified here apply to the the media independent interface (MII), reduced
gigabit media independent interface (RGMII), and reduced ten-bit interface (RTBI) signals except
management data input/output (MDIO) and management data clock (MDC). The MII interface is defined
for 3.3 V, and the RGMII and RTBI interfaces are defined for 2.5 V. The RGMII and RTBI interfaces
follow the Hewlett-Packard Reduced Pin-Count Interface for Gigabit Ethernet Physical Layer Device
Specification, Version 1.2a (9/22/2000). The electrical characteristics for MDIO and MDC are specified
8.1.1
TSEC DC Electrical Characteristics
MII, RGMII, and RTBI drivers and receivers comply with the DC parametric attributes specified in
Table 19 and Table 20. The RGMII and RTBI signals in Table 20 are based on a 2.5-V CMOS interface
voltage as defined by JEDEC EIA/JESD8-5.

Notes:
1. The symbol VIN, in this case, represents the LVIN symbol referenced in Table 1 and Table 2.
2. MII pins not needed for RGMII or RTBI operation are powered by the OVDD supply.
