3 Description

The DS90UH983-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 DS90UH983-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 720p and 1080p resolutions

with 24 bit color depth over a single/dual link as well

as HDCP v1.4 support when paired with an HDCPcapable

deserializer.
