DS90UH941AS-Q1 2K DSI to FPD-Link III bridge serializer with video splitting and HDCP

Description

The DS90UH941AS-Q1 is a dual DSI to FPD-Link III bridge serializer designed for automotive infotainment applications. When paired with an FPD-Link III DS90UH940N-Q1, DS90UH948-Q1, DS90UH924-Q1, DS90UH926-Q1, or DS90UH928-Q1 deserializer, the DS90UH941AS-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 DS90UH941AS-Q1 can support symmetric and asymmetric splitting.

The DS90UH941AS-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.

The DS90UH941AS-Q1 serializes a MIPI DSI input supporting video resolutions up to 2K, WUXGA and 1080p60 with 24-bit color depth. In backward compatible mode the DS90UH941AS-Q1 supports up to WXGA and 720p resolutions with 24-bit color depth over one differential link.

The DS90UH941AS-Q1 supports HDCP applications that have a HDCP cipher engine in the serializer and deserializer. DSI video data is encrypted before the data is sent to the FPD-Link III interface and decrypted at the deserializer.
