Kansal Mariam Banu Shaick Ibrahim
The LAN9252 is a 2/3-port EtherCAT® slave controller with dual integrated Ethernet PHYs which each contain a full-duplex TX transceiver and support 100 Mbps (100BASE-TX) operation. The LAN9252 supports HP Auto-MDIX, allowing the use of direct connect or cross-over LAN cables. 100BASE-FX is supported via an external fiber transceiver. The device can be configured as a 3-port slave, providing an additional MII port. This port can be connected to an external PHY, forming a tap along the current daisy chain, or to another LAN9252 creating a 4-port solution.
