Connector description
3.3.1
10/100 Ethernet connector
On board, there is a FastEthernet interface, made available by a Micrel
KSZ8091RBA 10Baset-T/100Base-Tx Transceiver interfaced to PX30
RMII interface.
The connector is type TRXCOM p/n TRJ19401BGNL or equivalent, with
2kV decoupling capacitor.
This interface is compatible only with Fast Ethernet (10/100Mbps) Networks. When connected
to Gigabit Ethernet Networks, the speed will be limited to 100Mbps.
For the connection, cables category Cat5e or better are required. Cables category Cat6 are
recommended for noise reduction and EMC compatibility issues, especially when the length of the cable is significant.
On the connector there are also two LEDs. Left LED is Yellow and shows 10/100 connection. The right LED blinks Green to show ACTIVITY presence.
