Texas Instruments DS90UH941AS-Q1 DSI to FPD-Link III Serializers
Texas Instruments DS90UH941AS-Q1 Dual DSI to FPD-Link III Bridge Serializers are designed for automotive infotainment applications. The DS90UH941AS-Q1, when paired with an FPD-Link III DS90UH940N-Q1, DS90UH948-Q1, DS90UH924-Q1, DS90UH926-Q1, or DS90UH928-Q1 deserializer, can supply 1- or 2-lane high-speed serial streams over 50Ω, single-ended coaxial cables or over 100Ω, differential shielded twisted-pair (STP) and shielded twisted quad (STQ) cables. The DS90UH941AS-Q1 can support symmetric and asymmetric splitting to respond to the rise in the number and variance of displays in infotainment systems.
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 using low-voltage differential signaling, data scrambling, and randomization. The Texas Instruments DS90UH941AS-Q1 can consolidate video data over two differential pairs to simplify system design and decrease the interconnect size and weight of the application.
