TLK110PTR

The TLK110PTR is a single-port Ethernet Physical-layer Transceiver for 10Base-T and 100Base-TX signalling. This device integrates all the physical-layer functions needed to transmit and receive data on standard twisted-pair cables. The TLK110 supports the standard Media Independent Interface (MII) and Reduced Media Independent Interface (RMII) for direct connection to a Media Access Controller (MAC). The TLK110 is designed for power-supply flexibility and can operate with a single 3.3V power supply or with combinations of 3.3V and 1.55V power supplies for reduced power operation. The TLK110 uses mixed-signal processing to perform equalization, data recovery and error correction to achieve robust operation over CAT 5 twisted-pair wiring. This device not only meets the requirements of IEEE 802.3, but maintains high margins in terms of cross-talk and alien noise. The TLK110 Ethernet PHY has a special Power Back Off mode to conserve power in systems with relatively short cables.
