Overview
The TLK106RHBR, produced by Texas Instruments, is an industrial temperature, single-port 10/100-Mbps Ethernet physical layer transceiver. This device integrates all the physical-layer functions necessary for transmitting and receiving data on standard twisted-pair cables, supporting both 10Base-T and 100Base-TX signaling. The TLK106RHBR is designed for power-supply flexibility, operating with either a single 3.3V power supply or combinations of 3.3V and 1.55V power supplies for reduced power operation. It features low power consumption, programmable power back off, and low deterministic latency, making it suitable for various industrial and embedded applications.
