Audio/video converter for DisplayPort, HDMI unleashed

18 Jun 2012

STMicroelectronics has offered what it claims as the world's first high-speed active-protocol bi-directional converters for managing audio and video signals between DisplayPort and HDMI. According to the company, the "Mystique" family of products target the two most common digital-display interface technologies used in computer and consumer electronics.

The Mystique audio/video converter SoC's bi-directional conversion of HDMI 1.4 and DisplayPort 1.2 formats ensures seamless connectivity among various consumer and commercial computer and multimedia equipment such as Blu-ray disk players, game consoles, docking stations , laptops, tablets, digital signs and Thunderbolt devices. The converters also enable the ultimate multimedia experience by supporting the new ultra high-definition 4Kx2K displays (4096x2160p is four times Full HD) and 7.1-channel surround sound, added ST.

The Mystique converters accept and output DisplayPort 1.2 High Bit Rate 2 data, at 5.4Gb/s per lane, so only two data pairs are required to drive a Full HD 120Hz TV, minimizing cable and component cost and signal routing space in product design. OEMs can expand their connectivity solutions across a broad range of existing and new products by developing external dongles and docking stations supporting both HDMI and DisplayPort standards for enterprise, mobile and home use.

The DisplayPort 1.2 standard enables wider bandwidth data of up to 21.6Gb/s, and multistream transmission through a single cable for 'daisy chain' and 'tile' display applications.

The products in the Mystique family include the STDP2600—HDMI 1.4 to Dual-Mode DisplayPort (DP++) converter, the STDP2650—DisplayPort 1.2 to HDMI 1.4 converter, and the STDP2690 – DisplayPort 1.2 to Dual-Mode DisplayPort (DP++) converter. All devices are sampling now and are targeted for high-volume OEM and ODM business.
