Texas Instruments DS90UB983-Q1 4K Bridge Serializer

Texas Instruments DS90UB983-Q1 4K DisplayPort/eDP to FPD-Link IV Bridge Serializer, in conjunction with an FPD-Link IV deserializer, 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 can support video resolution up to 4K with 30-bit color. 8b10b encoded DP data is serialized onto an FPD-Link IV interface output. The FPD-Link IV interface supports audio and video data transmission and full duplex control, including GPIO and I2C data over a single or dual channel. Consolidating video data and control over FPD-Link IV lanes reduces the interconnect size and weight and simplifies system design. EMI is minimized by using low voltage differential signaling, data scrambling, SSCG, and randomization. In backward compatible mode, the Texas Instruments DS90UB983-Q1 supports up to 720p and 1080p resolutions with 24-bit color depth over a single/dual link.
