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)—GMII/MII/TBI/RGMII/RTBI Electrical Characteristics
The electrical characteristics specified here apply to gigabit media independent interface (GMII), the
media independent interface (MII), ten-bit interface (TBI), 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, GMII, and TBI interfaces are 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 in Section 8.3,

Notes:
1. Actual attainable baud rate will be limited by the latency of interrupt processing.
2. The middle of a start bit is detected as the 8th sampled 0 after the 1-to-0 transition of the start bit. Subsequent bit values are
sampled each 16th sample.
