LMH0344SQE Description

Short technical summary and product information.

The Texas Instruments LMH0344SQE is an active 3-Gbps HD/SD SDI adaptive cable equalizer. It is engineered to equalize data transmitted over various media, including cables with dispersive loss characteristics.

 

This device operates over a wide range of data rates, from 125 Mbps to 2.97 Gbps, and is compliant with ST 424, ST 292, ST 344, and ST 259 standards. It supports DVB-ASI at 270 Mbps. The LMH0344SQE can equalize up to 120 meters of Belden 1694A cable at 2.97 Gbps, up to 140 meters at 1.485 Gbps, and up to 400 meters at 270 Mbps. It features manual bypass, output mute with a programmable threshold, and single-ended or differential input.

 

The LMH0344SQE is available in a 16-pin WQFN package with dimensions of 4 mm x 4 mm. It operates on a single 3.3-V supply with a typical power consumption of 280 mW. The component is designed for an industrial temperature range of -40°C to +85°C and has an HBM ESD rating of 8 kV. The WQFN version is footprint compatible with LMH0044, LMH0384, and LMH0074.
