DS90UB947-Q1 1080p OpenLDI to FPD-Link III Serializer 1 Features 3 Description 1 Supports Clock Frequency up to 170 MHz for The DS90UB947-Q1 is an OpenLDI to FPD-Link III. WUXGA (1920x1200) and 1080p60 Resolutions bridge device which, in conjunction with the FPD-Link III DS90UB940-Q1/DS90UB948-Q1 deserializers, with 24-Bit Color Depth provides 1-lane or 2-lane high-speed serial streams Single and Dual FPD-Link III Outputs over cost-effective 50 single-ended coaxial or 100.

2 Single link : Up to 96 MHz Pixel Clock differential shielded twisted-pair (STP) cables. It Dual link : Up to 170 MHz Pixel Clock serializes an OpenLDI input supporting video resolutions up to WUXGA and 1080p60 with 24-bit Single and Dual OpenLDI (LVDS) Receiver color depth. Configurable 18-Bit RGB or 24-Bit RGB. The FPD-Link III interface supports video and audio High Speed Back Channel Supporting GPIO up to data transmission and full duplex control, including 2 Mbps I2C and SPI communication, over the same Supports up to 15 Meters of Cable with Automatic differential link .

3 Consolidation of video data and Temperature and Aging Compensation control over two differential pairs reduces the interconnect size and weight and simplifies system I2C (Master/Slave) with 1 Mbps Fast-Mode Plus design. EMI is minimized by the use of low voltage SPI Pass-Through Interface differential signaling, data scrambling, and Backward compatible with DS90UB926Q-Q1 and randomization. In backward compatible mode, the DS90UB928Q-Q1 FPD-Link III Deserializers device supports up to WXGA and 720p resolutions Automotive Grade Product: AEC-Q100 Grade 2 with 24-bit color depth over a single differential link .

4 Qualified The DS90UB947-Q1 supports multi-channel audio received through an external I2S interface. Audio 2 Applications data received by the device is encrypted and sent over the FPD-Link III interface where it is regenerated Automotive Infotainment: by the deserializer.
