TI TLK106RHBT

The TLK10x is a single-port Ethernet PHY for 10Base-T and 100Base-TX signaling. The device integrates all physical layer functions required to transmit and receive data over standard twisted-pair cables. The TLK10x supports the standard Media Independent Interface (MII) and Reduced Media Independent Interface (RMII) required for direct connection to a Media Access Controller (MAC). The TLK10x is designed for power supply flexibility, operating either from a single 3.3V supply or a reduced supply combining 3.3V and 1.55V. The TLK10x uses mixed-signal processing to perform equalization, data recovery, and error correction for robust operation over Category 5 (CAT 5) twisted-pair cables. The device not only meets IEEE 802.3 requirements but also maintains high tolerance to crosstalk and external noise. The TLK10x Ethernet PHY features a special power-back-off mode to reduce power consumption in systems with relatively short cable lengths. This mode provides the flexibility to lower system power consumption when the system does not need to drive the standard IEEE 802.3 100m cable length, or the extended 150m error-free cable range of the TLK10x.
