Benefits
Facilitates large package size requirement in new Ethernet
applications.
Ethernet traffic between Port 1 and Port 2 are sustained while
the MII interface (Port 3) is shut down. This allows the device
connected to the MII interface to enter a power saving mode.
Enables the implementation of advanced QoS policies.
Enables the implementation of Ethernet ring network for
industrial control and automotive applications.
Eliminates expensive external 50MHz oscillator for the RMII
mode.
Allows identification of common cabling problems, including
those not addressed by IEEE. Simplifies network deployment
and reduces network downtime.
