Texas Instruments DS90UH981-Q1 Bridge Serializer
Texas Instruments DS90UH981-Q1 4K DSI to FPD-Link IV Bridge Serializer, in conjunction with an FPD-Link IV deserializer, the chipset provides a high-speed serialized interface over low-cost 50Ω coax or STP cables. The DS90UH981-Q1 is a D-PHY v1.2 compliant device that serializes a MIPI DSI input supporting video resolutions including 4K with 30-bit color depth. The FPD-Link IV interface supports video and audio data transmission and full duplex control, including I2C and GPIO data over a single or dual channel. Consolidating video data and control over two FPD-Link IV lanes reduces the interconnect size and weight and simplifies system design. EMI is minimized by using low voltage differential signaling, data scrambling, SSCG, and randomization. In backward compatible mode, the Texas Instruments DS90UH981-Q1 supports up to 720p and 1080p resolutions with 24-bit color depth over a single/dual link, as well as HDCP v1.4 support when paired with an HDCP-capable deserializer. The device is interoperable in ADAS-compatible mode with 936, 95x, 96x, and 97x deserializers supporting resolutions up to 8MP+/40fps.Features
