explain
DS90UB941AS-Q1 is a two-way DSI to FPD-Link III bridge serializer designed for automotive infotainment applications. When used with FPD-Link III DS90UB940N-Q1, DS90UB948-Q1, DS90UB924-Q1, DS90UB926Q-Q1, or DS90UB928Q-Q1 deserializer, DS90UB941AS-Q1 can provide single or dual channel high-speed serial flow through cost-effective 50 Ω single ended coaxial cable or 100 Ω differential shielded twisted pair (STP) and shielded quad (STQ) cable. In order to cope with the increase in the number and difference of displays in the infotainment system, DS90UB941AS-Q1 can support symmetrical and asymmetrical separation.
The DS90UB941AS-Q1 can integrate video data on two differential pairs to simplify system design and reduce the size and weight of the application interconnect. FPD-Link III interface supports video and audio data transmission and full duplex control, including I2C communication on the same high-speed serial Link and up to eight I2S audio channels. The EMI is minimized by using low voltage differential signaling, data reordering, and random generation.
