The DS90UB941ASRTDRQ1 Electronic Components is a Display Serial Interface (DSI) to FPD-Link III Bridge device that, in conjunction with the DS90UB940N-Q1, DS90UB948-Q1 deserializers over two low-cost, 50 Ω coaxial or two 100 Ω shielded twisted-pair (STP) cables, transmits high-resolution video, audio, and control information. Each of the dual DSI links has (4 lanes + 1 clock). They support video resolutions up to 2K with 24-bit color depth, and translates into dual-pair high-speed serialized interfaces. 

The serial bus scheme, FPD-Link III, supports video and audio data transmission and full duplex control including I2C communication over two differential links. Consolidation of video data and control over two differential pairs reduce the interconnect size and weight, while also eliminating skew issues and simplifying 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 WXGA and 720p resolution with 24-bit color transmit over one differential link to the DS90UB924-Q1, DS90UB926-Q1 or DS90UB928-Q1 deserializers.

The DS90UB941AS-Q1 is a dual DSI to FPD-Link III bridge serializer designed for automotive infotainment applications. When paired with an FPD-Link III DS90UB940N-Q1, DS90UB948-Q1, DS90UB924-Q1, DS90UB926Q-Q1 or DS90UB928Q-Q1 deserializer, the DS90UB941AS-Q1 can supply 1- or 2-lane highspeed serial streams over cost-effective, 50 Ω, singleended coaxial cables or over 100 Ω, differential shielded twisted-pair (STP) and shielded twisted-quad (STQ) cables. In response to the rise in number and variance of displays in infotainment systems, the DS90UB941AS-Q1 can support symmetric and asymmetric splitting.
