8.1.1
eTSEC DC Electrical Characteristics
All MII and RGMII drivers and receivers comply with the DC parametric attributes specified in Table 21
and Table 22. The RGMII signals are based on a 2.5-V CMOS interface voltage as defined by JEDEC
EIA/JESD8-5.
8.2
MII and RGMII AC Timing Specifications
The AC timing specifications for MII and RGMII are presented in this section.
