Ethernet PHY
Ethernet support is provided via the National Semiconductor DP83848C
Ethernet Physical Layer Transceiver chip and an RJ-45 connector (J5).
lists Ethernet PHY board reference and manufacturing
information.
The DP83848C device has the following features:
■
Single Port 10/100 Mb/s Ethernet Physical Layer Transceiver
■
Supports both 100Base-T and 10Base-T Ethernet protocols
■
Supports Auto-MDIX for 10/100 Mb/s
The DP83848C is one port Fast Ethernet PHY Transceivers supporting
IEEE 802.3 physical layer applications at 10 Mbps and 100 Mbps. The
DP83848C provides Media Independent Interface (MII) to connect
DP83848C to a MAC in the FPGA.
