eTSEC (10/100/1000 Mbps)—MII/RMII/RGMII/RTBI Electrical
Characteristics
The electrical characteristics specified here apply to all the media-independent interface (MII), reduced
gigabit MII (RGMII), and reduced ten-bit interface (RTBI) signals except management data input/output
(MDIO) and management data clock (MDC). The MII and RMII is defined for 3.3 V, while the RGMII,
and RTBI can operate at 2.5 V. The RGMII and RTBI 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 9.3, “Ethernet Management
9.1.1
MII, RMII, RGMII, and RTBI DC Electrical Characteristics
All MII, RMII drivers and receivers comply with the DC parametric attributes specified in Table 23 for
3.3-V operation and RGMII, RTBI drivers and receivers comply with the DC parametric attributes
specified in Table 24. The RGMII and RTBI signals are based on a 2.5 V CMOS interface voltage as
defined by JEDEC EIA/JESD8–5.
NOTE
eTSEC should be interfaced with peripheral operating at same voltage level.
