Industry's first 12G UHD-SDI reclocker for 4K broadcast video systems

TI samples quad reclocker, enables 4K video transmission at 60 Hz over single coaxial cable link

Aug 29, 2013

DALLAS, Aug. 29, 2013 /PRNewswire/ -- Texas Instruments (TI) (NASDAQ: TXN) today announced the industry's first 12G ultra-high-definition (UHD) serial digital interface (SDI) reclocker with integrated signal conditioning. The four-channel LMH1256 doubles the transmission rate of competing 6G devices, allowing broadcast video equipment to capture, record and play back 4K video signals at 60 Hz over a single link of coaxial cable. The LMH1256 reclocker addresses next-generation systems, including digital video routers, switches, encoders/decoders, modular cards, multi-viewers and display monitors. For more information and to order samples, visit www.ti.com/lmh1256-pr.

TI will demonstrate the LMH1256 operating with an Altera Stratix® V GX development board at IBC 2013 in Amsterdam, September 13-17 at Hall 11, Booth #G41.

The emerging 4K UHD standard delivers four times the image resolution compared to current 1080p HD video equipment. By enabling a screen display resolution of 3840 by 2160 pixels, 4K UHD presents video in much greater detail, offering consumers a more immersive TV viewing experience.

Key features and benefits of the LMH1256:

  • Highest transmission rate available: Enables broadcast video equipment to transmit 4K video signals at 60 Hz over a single coaxial cable link, and deliver multi-rate operation at transmission speeds from 270 Mbps to 11.868 Gbps. The LMH1256 recovers the serial clock and retimes the serial data stream to suppress accumulated jitter.
  • Integrated eye monitor: On-chip oscilloscope probe enables system designers to examine transmitted signals at any point in the system for faster time-to-market. Equipment end users save time and repair costs during debug and installation via the eye monitor's ability to detect a faulty signal or cable.
  • Ultra-low power consumption: 200-mW typical power consumption enables system designers to pack in more channels and features into smaller frames.
  • Reduced board size: As the number of video inputs/outputs increase, the LMH1256's four channels help customers design multi-channel equipment with smaller board size and footprint.

Tools and support
An evaluation module (EVM) is available to help accelerate the development of 4K UHD-SDI video systems. The LMH1256EVM can be purchased for a suggested retail price of USD$699. An IBIS-AMI model is also available to verify board signal integrity requirements.

Engineers designing with the LMH1256 can ask questions and get answers from TI experts in the TI E2E™ Community High Speed Interface Forum.

Availability, packaging and pricing
Samples of the LMH1256 are available today in a 48-pin, 7-mm by 7-mm QFN package, with production volumes expected in 1Q 2104. Pre-production pricing is currently set at US$35 in 1,000-unit quantities.
