Connecting Ethernet device to PLC chipset



Jan 1, 1970
Hello all,

I have developed an Ethernet solution and I am hoping to be able to connect
it to a HomePlug chipset. The device that I am looking at is the INT5200
from intellon ( The
product brief states that it contains the following connections;

A USB1.1 device interface for connection to a USB host
An MII PHY (IEEE 802.3u) / GPSI interface for interconnection to
microcontrollers or Ethernet controllers
An MII Host / DTE interface (IEEE 802.3u) for direct connection to an
Ethernet PHY

USB is obvious, an MII Host / DTE interface is also clearly an MII
connection, and GPSI is a serial communication channel between it and a

I am unclear, however, on the meaning of An MII PHY in this context. Is this
intended for connecting Ethernet controllers directly on the differential
i/o?? If anyone could clarify this for me then this is highly appreciated.

Best Regards,
