Q:Active DisplayPort cable

Intersil Corp. rolls its Q:Active HD line of high-performance DisplayPort cables.

Powered by the Intersil's Q:Active analog signal processing technology, these "active cables" support the full 8.64Gbit/s bandwidth HBR of DisplayPort 1.1a, enabling a resolution of 2,560p x 1,600p through up to 50m of copper cablefar exceeding the capabilities of interconnects which are currently limited to lengths of 3 meters or less. They also support the upcoming DisplayPort 1.2 specification HBR2 that doubles the resolution and color depth with an aggregate data rate of 17.28Gbit/s.

"Clearly this is a breakthrough for consumer interconnects at a time that's right", said Ken Fleck, founder, Fleck Research, and a veteran in the interconnect industry. "Intersil's approach, technology, and user benefits are impressive."

"It is very pleasing to see innovative solutions like Intersil's Mini DisplayPort (mDP)-to-DP ultrathin active cables introduced so shortly after the adoption of the standard. This interconnect will be an attractive addition to technologies available to DisplayPort end users," said Bruce Montag, chairman of the Video Electronics Standards Association."

"We are extremely proud to introduce our Q:Active HD DisplayPort copper cable assemblies," said Huibert Verhoeven, VP and general manager of the high-speed products group, Intersil. "These ultrathin long-haul interconnects will enable high-speed digital video and audio data transmission for the entire range of display applications, from extreme gaming to commercial and personal video HyperWalls. Our Q:Active technology, now proven in High Performance Computing, is making its way to the consumer market with unprecedented benefits."

mDP is the small connector standard recently adopted by the VESA for the newest portable PCs, ultrathin netbooks and notebooks. The small form-factor of the mDP connector makes it difficult to utilize traditional thick wire gauge cable, making the Q:Active ultrathin cable technology an essential alternative.

These active cables use Intersil high-speed CMOS devices that are embedded directly into the connector, and compensate for channel impairments such as skew, attenuation, group delay and crosstalk presented by the copper cable. They are entirely analog for low power and small size, yet they deliver the industry's highest performance. They enable current and future DisplayPort traffic to run on copper twinax cable just 2mm in diameter30 percent thinner than fiber optics and 90 percent thinner than Category 6a structured cabling. Alternatively, Q:Active technology can increase distance on traditional copper by as much as 600 percent. This allows gamers, studios and stadiums to interconnect without the hefty power consumption of fiber optic lasers and receivers or additional electronic repeater boxes.

Market research firm In-Stat forecasts that over 600 million DisplayPort enabled devices will be shipped in 2012, a growth rate of 194 percent compounded annually from 2008 to 2013. Applications for these cables include projection, extreme gaming, rendering studios, supercomputing, HyperWalls, and stadiums.

Intersil's Q:Active technology is a broadly deployed active cable format with installations in Top 500 supplied supercomputers, raster image processors, servers, storage farms and data centers worldwide. These switches and supercomputers can consume up to 30,000 ports of Q:Active technology per individual installation.

Q:Active HD DisplayPort cable pricing starts at $89 per cable.
