3 Description

DS90UB981-Q1 is a MIPI DSI to FPD-Link III/IV

bridge device. In conjunction with an FPD-Link

IV deserializer, the chipset provides a high-speed

serialized interface over low-cost 50Ω coax or

STP cables. The DS90UB981-Q1 is a D-PHY v1.2

compliant device that serializes a MIPI DSI input

supporting video resolutions including 4K with 30-bit

color depth. 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 two 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 devices supports

up to 720p and 1080p resolutions with 24-bit color

depth over a single/dual link. In ADAS compatible

mode, the device is interoperable with 936, 95x, 96x &

97x deserializers supporting resolutions up to 8MP+/

40fps.
