TI DS90UB927QSQX/NOPB

The DS90UB927Q-Q1 serializer works in conjunction with the DS90UB928Q-Q1 or DS90UB926Q-Q1 deserializer to provide a complete digital interface for high-speed parallel transmission of video, audio, and control data in automotive display and image sensing applications. This chipset is well suited for in-vehicle video display systems in HD format and automotive vision systems with megapixel-class resolution. The DS90UB927Q-Q1 integrates an embedded bidirectional control channel and low-latency GPIO control. The device converts the FPD-Link video interface to a single-pair high-speed serialized interface. The FPD-Link III serial bus solution supports full-duplex control with high-speed forward channel data transmission and low-speed reverse channel communication over a single differential link. Combining audio, video, and control data over a single differential pair reduces interconnect size and weight, while also eliminating skew issues and simplifying system design. The DS90UB927Q-Q1 serializer embeds a clock and level-shifts signals to high-speed low-voltage differential signaling. Up to 24 RGB data bits are serialized along with 3 video control signals and up to 4 IS data inputs. With the FPD-Link data interface, the device connects easily to data sources while reducing EMI and bus width. EMI on the high-speed FPD-Link III bus is minimized through the use of low-voltage differential signaling, data scrambling and randomization, and DC balance features.
