Ethernet: Three-Speed Ethernet, MII Management
This section provides the AC and DC electrical characteristics for three-speed, 10/100/1000, and MII
management. MPC8308 supports dual Ethernet controllers.
8.1
Enhanced Three-Speed Ethernet Controller (eTSEC)
(10/100/1000 Mbps)—MII/RGMII Electrical Characteristics
The electrical characteristics specified here apply to all the media independent interface (MII) and reduced
gigabit media independent interface (RGMII) signals except management data input/output (MDIO) and
management data clock (MDC). The RGMII interface is defined for 2.5 V, while the MII interface can be
operated at 3.3 V. The RGMII interface follows 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, “Ethernet Management Interface

Notes:
1. Actual attainable baud rate is 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.
