DisplayPort

DisplayPort is the latest high definition display interface standard, launched by VESA. Like DVI and HDMI, it uses multi lane serial transmission but DisplayPort can also transmit power so that remote circuits can be powered from the image source or the monitor.

The current DisplayPort standard is v1.1. This defines up to 2.7Gbits/s per lane – and up to 4 lanes giving a maximum of 10.4Gbit/s total transport speed.

EqcoLogic has developed a new 4 lane equalizer, the EQCO2754, to enable long-haul operation of DisplayPort. The device can be embedded in cables or connectors, working off the power provided by the DisplayPort display connector. The EQCO2754 works at up to 5.4Gbit/s per lane, anticipating a new 2x standard. The extra speed can be used to allow full resolution monitors to be daisy-chained together, for applications such as those in medicine, education and financial trading. It offers extended reach (up to 15m @ 5.4Gbit/s), and at all lengths improves signal integrity by integrated de-skew.
