NEC Develops Ultra High-Speed ​​Transfer Interface Overwhelming USB 3.0, Available with Low-Cost USB Cable

"USB 3.0" which realized high-speed transfer of up to 4.8 Gbps corresponding to 10 times the USB 2.0 is gathering expectations as the next-generation interface, but the ultra high-speed transfer interface realizing the overwhelming speed of USB 3.0 is NEC It is said that it developed.

It is said that ultra high-speed communication becomes possible with a cheap USB cable.

Details are as follows.
Development of next-generation interface circuit technology realizing super high-speed communication between consumer devices (2 April 2009): Press Release | NEC

According to this release, NEC can use ultra high-speed communication while using "low cost, flexible but signal-prone transmission cable" such as cable used for USB 2.0 as a communication interface between consumer devices It is said that he developed a circuit technology to make it.

Conventionally, when transferring data at high speed by using an inexpensive cable, it was necessary to completely correct the distortion of the generated signal waveform with the circuit, so that the processing capability of the circuit was a bottleneck in the communication speed about.

In the new technique, the signal is received intentionally leaving a certain amount of distortion, and correction processing is performed every time on one input data, whereas for each of the four input data, 1 By executing the correction process only times, it is said that super high-speed communication equivalent to that when using expensive cables, which are hard to cause distortion, can be realized.

The transfer time when actually transmitting 2 hours of high definition video content using "USB 2.0" was about 14 minutes, and when using "USB 3.0" it was about 80 seconds, It seems that it was able to transfer in about 22 seconds when using the new communication interface developed this time. It is exactly overwhelming.

Although it is a very breakthrough technology, NEC is proceeding with aggressive research and development in the future for commercialization of this technology.
