A cable driver, claimed to be the industry’s first to support uncompressed 4K UHD video transmission using SDI and 10GbE protocols, has been introduced by Texas Instruments. The LMH1218 provides engineers with the flexibility to design video infrastructure equipment for SDI or IP formats with a single component.

Featuring an integrated reclocker, the device supports both coax cable and optical media for uncompressed video transmission inside buildings and over long-haul networks. Saving up to 40% board space compared to competitive solutions, this integration simplifies the design of applications such as broadcast video routers and switches, digital signage, test and measurement equipment, medical imaging and security and surveillance equipment.

“With broadcasters and video professionals looking to use 60p and create more 4K content, upgrading SDI infrastructure to use a single cable to transmit 12Gb/s of data for 4K uncompressed video transmission is essential,” said Grant Petty, CEO, Blackmagic Design. “The integrated capabilities of TI’s LMH1218 cable driver are helping us quickly design new and improved 12Gb/s SDI products, and I can’t wait to see the new content. In particular, 60p is something that broadcasters are starting to use now; enabling 12Gb/s SDI throughout will allow them to build out an efficient 4K workflow to handle 60p.”

The LMH1218, which is offered in a 4x4mm QFN package, is available now, priced at $25 and sold in 1,000-unit quantities. The LMH1218 evaluation module allows designers to quickly and easily evaluate device features and performance. The LMH1218EVM is available now and priced at $449.

The capabilities of the LMH1218 will be exhibited at the National Association of Broadcasters Show 2015, which takes place from 11th to 16th April in Las Vegas, Nevada. TI will be located at booth N8519.
