The TLK100 is a single-port Ethernet PHY for 10BaseT and 100Base TX signaling. It integrates all the physical-layer functions needed to transmit and receive data on standard twisted-pair cables. This device supports the standard Media Independent Interface (MII) for direct connection to a Media Access Controller (MAC).

The TLK100 is designed for power-supply flexibility, and can operate with a single 3.3V power supply or with combinations of 3.3V, 1.8V, and 1.1V power supplies for reduced power operation.

The TLK100 uses mixed-signal processing to perform equalization, data recovery, and error correction to achieve robust operation over CAT 5 twisted-pair wiring. It not only meets the requirements of IEEE 802.3, but maintains high margins in terms of cross-talk and alien noise.
