  • Symmetric and asymmetric video splitting

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 high-speed serial streams over cost-effective, 50 Ω, single-ended 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.

The DS90UB941AS-Q1 can consolidate video data over two differential pairs to simplify system design and decrease the interconnect size and weight of the application.

The FPD-Link III interface supports video and audio data transmission and full duplex control, including I2C communication and up to eight I2S audio channels over the same high-speed serial link. EMI is minimized by the use of low voltage differential signaling, data scrambling, and randomization.
