STMicroelectronics has unveiled the Mystique family of high-speed active-protocol bi-directional converters for managing audio and video signals between the two most common digital-display interface technologies used in computer and consumer electronicsDisplayPort and HDMI.

The Mystique SoCs enable a multimedia experience that supports 4Kx2K displays (4,096 x 2,160p or 4 times Full HD) and 7.1-channel surround sound. The 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.

Mystique technical features include:

  • Dual-mode DisplayPort 1.2 /HDMI1.4-compliant transmitter and receiver
  • RGB and YUV video formats with deep color support up to 16 bits/color
  • High-Bandwidth Digital Content Protection (HDCP) 1.3 with on-chip keys & HDCP repeater capability
  • Adaptive equalization and pre-emphasis for long-reach cable support
  • Spread-spectrum technique reduces Electro-Magnetic Interference
  • Embedded DisplayPort (eDP) authentication support
  • Supports 4Kx2K / 3D FHD 120Hz video; conversion between frame sequential format and stacked top-bottom
  • Supports audio up to 7.1CH from 32kHz to 192kHz and high bit-rate audio
  • Optimized for low-power operation

The SoCs are said to ensure seamless connectivity among various consumer and commercial computer and multimedia equipment, including Blu-ray disk players, game consoles, docking stations , laptops, tablets, digital signs, and Thunderbolt devices.

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