3 Description

The DS90UH984-Q1 is an FPD-Link IV to DisplayPort

(DP) / Embedded DisplayPort (eDP) bridge device.

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

DS90UH984-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 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.
