TLK105LRHBR TI Ethernet PHY | 32-VQFN (5x5) | 10/100BASE-T, Auto-MDIX

Product Overview

The TLK105LRHBR is a low-power, single-port 10/100BASE-T Ethernet physical layer transceiver (PHY) from Texas Instruments. It integrates all the physical-layer functions needed to transmit and receive data over standard twisted-pair cables. The device supports the MII (Media Independent Interface) and RMII (Reduced MII) interfaces, enabling seamless connection to MAC (Media Access Control) layers. Housed in a compact 32-VQFN (5x5 mm) package, it is ideal for space-constrained applications requiring reliable Ethernet connectivity.
