3 Description

The DS90UB988-Q1 is an FPD-Link IV to OpenLDI

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 DS90UB988-Q1 supports OpenLDI (10 LVDS

data lanes + 2 clocks) interface with video up to

420MHz PCLK. This provides a bridge between

sources such as GPUs to connect to existing LVDS

based displays or application processors.

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 and control data 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 .
