Overview

The TLK110PT is a single-port 10/100 Ethernet physical layer (PHY) transceiver designed for industrial environments. It supports both MII and RMII interfaces for flexible connection to a MAC, and it is engineered for long cable reaches up to 150 meters for 100Base-TX. This device features robust cable diagnostics and low deterministic latency suitable for real-time industrial networking.

Why Choose This Part

The transceiver offers exceptional cable reach, maintaining error-free 100Base-T operation up to 150 meters and 10Base-T up to 300 meters. Its low power consumption (203mW in 100Base-TX) and advanced Wake-on-LAN (WOL) modes help reduce thermal load in sealed industrial enclosures. Integrated cable diagnostics and programmable fast link down modes provide enhanced system-level reliability and troubleshooting capabilities.

Applications

Industrial Ethernet
Ideal for EtherCAT, PROFINET, and Ethernet/IP applications requiring low deterministic latency and high EMI resilience.
Factory Automation
Used in PLC and motor drive systems where reliable 10/100 Mbps communication is required over long cable runs.
Smart Grid Infrastructure
Integrates into power distribution equipment requiring reliable data transmission in electrically noisy environments.

Getting Started

To evaluate the TLK110PT, utilize the TLK110CUSTEVB evaluation board to test MII/RMII performance and power consumption. Connect the device via the Serial Management Interface (MDC/MDIO) to your host processor to configure registers and access the integrated cable diagnostic tools. Design the PCB with a single 3.3V supply and a 25MHz reference clock while following high-speed differential pair routing guidelines for the MDI signals.
