Ny chip baner vej for 4K videosystemer
En ny reclocker chip fra Texas Instruments gør det muligt at overføre 4K videotransmissioner ved 60 Hz over et koaxkabel (in english).
Texas Instruments (TI) has 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.
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 3048 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.
