TI DS90UB983RTDRQ1

The DS90UB983-Q1 is a DisplayPort/eDP to FPDLink III/IV bridge device. In conjunction with an FPDLink IV deserializer, the chipset provides a high-speed serialized interface over low-cost 50Ω coax or STP cables. The DS90UB983-Q1 is a VESA DP Standard v1.4 compatible device that supports advanced features such as MST, HBR3, and SuperFrame formats. The device is capable of supporting video resolution up to 4K resolutions with 30-bit color. 8b10b encoded DP data is serialized onto an FPD-Link IV interface output. The FPD-Link IV interface supports video and audio data transmission and full duplex control, including I²C, and GPIO data over a single channel or dual channels. Consolidation of video data and control over FPD-Link IV lanes reduces the interconnect size and weight and simplifies system design. EMI is minimized by the use of low voltage differential signaling, data scrambling, SSCG, and randomization. In backward compatible mode, the device supports up to 720ρ and 1080ρ resolutions with 24-bit color depth over a single/dual link.
