LMH1297RTVR Description

Short technical summary and product information.

The Texas Instruments LMH1297RTVR is an integrated circuit designed for serial digital interface (SDI) applications, specifically functioning as a video reclocker. This device supports advanced standards like 12G UHD-SDI, 6G, 3G, HD, and SD, making it suitable for professional video workflows. It is compatible with DVB-ASI and AES10 (MADI) standards.

 

The LMH1297RTVR features an integrated reclocker that locks to various SMPTE rates, including 11.88 Gbps, 5.94 Gbps, 2.97 Gbps, 1.485 Gbps, and 270 Mbps. It includes on-chip 75-Ohm termination and a return loss compensation network. The device can operate in either an equalizer (EQ) mode with adaptive cable equalization or a cable driver (CD) mode with dual differential outputs, both with integrated reclocking capabilities.

 

Packaged in a 32-WQFN (5x5) surface-mount configuration, the LMH1297RTVR is designed for efficient integration into printed circuit boards. It operates within a voltage range of 2.375V to 2.625V and has an operating temperature range of -40°C to 85°C. The part is compliant with RoHS3 standards and has an MSL rating of 1.
