Coax cable-based digital camera interface from Imperx moves video data as fast as 6.25 gigabits per second

May 4, 2011
BOCA RATON, Fla., 4 May 2011. Imperx Inc. in Boca Raton, Fla., is introducing the CoaXPress high-speed point-to-point serial communications link for high-resolution digital still-image and video cameras in aerospace and defense applications. The CoaXPress camera interface provides six gigabits per second and offers a coax cable slip ring for 360-degree camera rotation. The camera interface can help systems integrators achieve real-time image acquisition. It transmits video and connects cameras to frame grabbers through a standard 75-ohm coaxial cable. The interface also provides a 20-megabit-per-second uplink for communications and control.

The interface also provides a 20-megabit-per-second uplink for communications and control.Coax cable, rather than more expensive Ethernet cable, that transmits high-speed digital imagery has several advantages, Imperx officials say.

First, coax is acknowledged to be the best electrical medium for high-speed transfer, and are reliable and cost effective. Second, coax does not suffer from intra-pair skew, and has solid performance in electromagnetic interference. In addition, a wide variety of inexpensive coax cables enable systems designers to choose thick cables for long runs, and thin cables for short runs.

CoaXPress protocols provide for automatic link , camera, and host setup, and the camera interface can provide power to the camera over the coax cable. Available power is a nominal 13 Watts at 24 volts. Short circuit protection is available.
