This section provides the AC and DC electrical characteristics for enhanced three-speed and MII
management.
8.1
The electrical characteristics specified here apply to all gigabit media independent interface (GMII), 8-bit
FIFO interface (FIFO), serial 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). The 8-bit FIFO interface can operate at 3.3 or 2.5 V. The RGMII and RTBI interfaces are defined
for 2.5 V, while the MII, GMII, TBI, and RMII interfaces can be operated at 3.3 or 2.5 V. Whether the
GMII, MII, or TBI interface is operated at 3.3 or 2.5 V, the 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 9, “Ethernet Management Interface Electrical Characteristics.”

Notes:
1. CCB clock refers to the platform clock.
2. Actual attainable baud rate will be limited by the latency of interrupt processing.
3. The middle of a start bit is detected as the eighth sampled 0 after the 1-to-0 transition of the start bit. Subsequent bit values
