Key Features

The LMH0302SQ/NOPB is a high-speed serial digital interface cable driver developed by Texas Instruments for professional broadcast video systems. Designed to support data rates up to 2.97 Gbps, this device is ideal for standards such as SMPTE ST 424, ST 292, ST 344, and ST 259. It also supports DVB-ASI transmission at 270 Mbps. The 100 Ω differential input ensures excellent signal integrity, while the 75 Ω single-ended output is optimized for standard video transmission lines. With a selectable slew rate function, designers can adapt the signal shape to suit either SD or HD requirements, improving compatibility and minimizing jitter. Operating from a single 3.3 V supply and consuming minimal power, the LMH0302SQ/NOPB balances high performance with energy efficiency. Its compact 16-pin WQFN package allows it to integrate easily into dense PCB layouts.

Applications

Serial digital video interfaces in HD and SD broadcast systems
Digital video routers requiring high-speed, low-jitter output
Broadcast-grade distribution amplifiers with extended cable reach
High-definition video processors in professional editing consoles
Studio-grade signal transmission equipment using coaxial interfaces
