• Manufacturer Part Number: mpc8378e
• Description: Powerquicc Ii Pro Processor Hardware Specifications
• Manufacturer: Freescale Semiconductor, Inc

Ethernet: Enhanced Three-Speed Ethernet (eTSEC)
The MII and RMII interfaces are defined for 3.3 V, while the RGMII and RTBI interfaces can be operated
at 2.5 V. The SGMII interface conforms to the Serial-GMII Specification Version 1.8 with some
exceptions. The RGMII and RTBI interfaces follow the Reduced Gigabit Media-Independent Interface
(RGMII) Specification Version 1.3. The RMII interface follows the RMII Consortium RMII Specification
Version 1.2.
8.2.1
MII and RMII drivers and receivers comply with the DC parametric attributes specified in
Table
defined by JEDEC EIA/JESD8-5.
