Description

The TDES4940 is a V 3Link Enhanced Video to DisplayPort (DP) / Embedded DisplayPort (eDP) bridge device. In conjunction with a V 3Link Enhanced Video serializer, the chipset receives a high-speed serialized interface over low-cost 50 Ω coax or STP/STQ cables. The TDES4940 is a VESA DP v1.4a/eDP v1.4b compatible device that supports advanced features such as HBR3, and SuperFrame formats. The device supports video resolutions of 4K 30-bit color and higher. The V 3Link Enhanced Video supports video and audio data transmission and full duplex control, including I2C, and GPIO data over the same link. Consolidation of video data and control over V 3Link Enhanced Video lanes reduces the interconnect size and weight and simplifies system design. EMI is minimized by the use of low voltage differential signaling, data scrambling, and randomization. In compatible V 3Link mode, the device supports up to 2K resolutions with 24-bit color depth over a single/dual link as well as HDCP v1.4 support when paired with an HDCP capable serializer.
