In stock now at distributor Mouser Electronics is the TI DP83TD510E Ethernet physical layer (PHY) from Texas Instruments.

Featuring an extended cable reach of more than 2 km, the IEEE 802.3cg 10BASE-T1L-compliant transceiver eliminates the need for additional protocols, gateways and cables for higher-bandwidth communications, allowing designers to extend the reach of their industrial communications and automation applications without increasing cabling costs or system weight.

This Ethernet PHY is capable of transmitting 10-Mbps Ethernet signals up to 1.7 km through a single pair of twisted wires.

An extended cable reach of 1.5 km is more than the 200-m requirement of the IEEE 802.3cg 10BASE-T1L single-pair Ethernet specification.

The device includes integrated cable diagnostic tools with built-in loopback and self-test capabilities, simplifying design and debugging processes.

The PHY offers a very low-noise, coupled receiver architecture, allowing for extended cable reach and low power dissipation.

Ultra-low-power consumption is less than 38 mW at 1 V p2p.

The DP83TD510E features external MDI termination to support intrinsic safety requirements, and it supports RMII back-to-back mode for applications requiring cable reach beyond 2,000 meters.
