TLK105L - Texas Instruments

TLK105L Single Port 10/100Mbs Ethernet Physical Layer Transceiver

The TLK10xL is a single-port Ethernet PHY for 10Base-T and 100Base TX signaling, integrating all the physical-layer functions needed to transmit and receive data on standard twisted-pair cables. The device supports the standard Media Independent Interface (MII) and Reduced Media Independent Interface (RMII) for direct connection to a Media Access Controller.
