TLK105LRHBT Description

Short technical summary and product information.

The Texas Instruments TLK105LRHBT is an industrial-grade, single-port 10/100 Mbps Ethernet physical layer transceiver. It is designed for applications requiring reliable Ethernet connectivity.

 

Key electrical specifications include support for MII and RMII interfaces, with a duplex capability of Half. The device operates over an industrial temperature range of -40°C to 85°C. It offers features such as cable diagnostics with fast link down modes and support for IEEE 1588 time stamping with low deterministic latency.

 

This transceiver supports error-free 100Base-T operation up to 150 meters and 10Base-T operation up to 300 meters under typical conditions. It also includes Auto-MDIX for simplified network connections and a serial management interface. The TLK105LRHBT is available in a 32-VQFN (5x5 mm) package and is designed for surface mount installation.

 

Note: This product is not recommended for new designs. An alternate product, the DP83822IF, offers similar functionality with fiber support.
