DESCRIPTION  
The DS90UB927Q serializer, in conjunction with a DS90UB928Q or DS90UB926Q deserializer, provides a  
complete digital interface for concurrent transmission of high-speed video, audio, and control data for automotive  
display and image sensing applications.  
The chipset is ideally suited for automotive video display systens with HD formats and automotive vision systems  
with megapixel resolutions. The DS90UB927Q incorporates an embedded bidirectional control channel and low  
latency GPIO controls. This device translates a FPD-Link video interface into a single-pair high-speed serialized  
interface. The FPD-Link III serial bus scheme supports full duplex, high speed forward channel data transmission  
and low-speed back channel communication over a single differential link. Consolidation of audio, video, and  
control data over a single differential pair reduces the interconnect size and weight, while also eliminating skew  
issues and simplifying system design.  
The DS90UB927Q serializer embeds the clock and level shifts the signals to high-speed differential signaling. Up  
to 24 RGB data bits are serialized along with three video control signals, and up to four I2S data inputs.  
The FPD-Link data interface allows for easy interfacing with data sources while also minimizing EMI and bus  
width. EMI on the high-speed FPD-Link III bus is minimized using low voltage differential signaling, data  
scrambling and randomization, and dc-balancing.
