Texas Instruments DS90UB984-Q1 FPD-Link to eDP Bridge Deserializer

Texas Instruments DS90UB984-Q1 4K FPD-Link IV to eDP Bridge Deserializer, in conjunction with an FPD-Link IV serializer, the chipset receives a high-speed serialized interface over low-cost 50Ω coax or STP/STQ cables. The DS90UB984-Q1 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 FPD-Link IV interface 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 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, and randomization. In backward-compatible FPD-Link III mode, the Texas Instruments DS90UB984-Q1 supports up to 2K resolutions with 24-bit color depth over a single/dual link.
