• Description: Mpc8568e Powerquicc Iii Processor
• Manufacturer: Freescale Semiconductor, Inc

Specification Version 1.2 (3/20/1998). The electrical characteristics for MDIO and MDC are specified in
Section 8, “Ethernet Interface and MII Management.”
8.1.1
All GMII, MII, TBI, RGMII, RMII and RTBI drivers and receivers comply with the DC parametric
attributes specified in
RGMII, RMII or RTBI receiver may exceed the potential of the receiver’s power supply (that is, a GMII
driver powered from a 3.6-V supply driving V
Tolerance for dissimilar GMII driver and receiver supply potentials is implicit in these specifications. The
RGMII and RTBI signals are based on a 2.5-V CMOS interface voltage as defined by JEDEC
EIA/JESD8-5.
