3 Description
The DS90UB983-Q1 is a DisplayPort to FPD-Link 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 DS90UB983-Q1 is a VESA DP Standard
v1.4 compliant 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,
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.
