The LAN9252 is an 2/3 port EtherCAT slave controller with dual integrated Ethernet PHYs which each contain a full-duplex 100BASE-TX transceiver and support 100Mbps (100BASE-TX) operation. 100BASE-FX is supported via an external fiber transceiver.Each port receives an EtherCAT frame, performs frame checking and forwards it to the next port. Time stamps of received frames are generated when they are received. The Loop-back function of each port forwards the frames to the next logical port, if there is either no link at a port, or if the port is not available, or if the loop is closed for that port. The Loop-back function of port 0 forward the frames to the EtherCAT Processing Unit. The loop settings can be controlled by the EtherCAT master.
The EVB-LAN9252-3PORT supports two Integrated PHY's via on board RJ45 Connectors and one External PHY through MII interfaceThe EVB-LAN9252-3PORT supports SPI and SQI based PDI configurations with onboard PIC32MX and option to plug-in third part SOC's like Beagle Bone BlackOption for onboard Fiber Interface via SFP moduleThe onboard EEPROM to configure the EtherCAT salve configuration
