Texas Instruments DS90UB941AS-Q1 Bridge Serializers

Texas Instruments DS90UB941AS-Q1 DSI to FPD-Link III Bridge Serializers are ideal for automotive infotainment applications. The DS90UB941AS-Q1, when paired with an FPD-Link III DS90UB940N-Q1, DS90UB948-Q1, DS90UB924-Q1, DS90UB926Q-Q1 or DS90UB928Q-Q1 deserializer, can supply high-speed serial streams over single-ended coaxial cables. These devices supply high-speed serial streams over 100Ω, differential shielded twisted-pair (STP), and shielded twisted-quad (STQ) cables. The DS90UB941AS-Q1 can support symmetric and asymmetric splitting in response to the rise in the number and variance of displays in infotainment systems.

The DSI to FPD-Link III Bridge Serializers 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. This support includes I2C communication and up to eight I2S audio channels over the same high-speed serial link. Low voltage differential signaling, data scrambling, and randomization minimize the EMI.

The Texas Instruments DS90UB941AS-Q1 serializes a MIPI DSI input that supports a video resolution of up to 2K, WUXGA, and 1080p60 with 24-bit color depth. The device supports up to WXGA and 720p resolutions with 24-bit color depth over one differential link in backward-compatible mode.
