The DS90UB947-Q1 is an OpenLDI to FPD-Link III bridge device which, in conjunction with the FPD-Link III DS90UB940-Q1/DS90UB948-Q1 deserializers, provides 1-lane or 2-lane high-speed serial streams over cost-effective 50-Ω single-ended coaxial or 100-Ω differential shielded twisted-pair (STP) cables. It serializes an OpenLDI input supporting video resolutions up to WUXGA and 1080p60 with 24-bit color depth.

The FPD-Link III interface supports video and audio data transmission and full duplex control, including I2C and SPI communication, over the same differential link. Consolidation of video data and control over two differential pairs reduces the interconnect size and weight and simplifies system design. EMI is minimized by the use of low voltage differential signaling, data scrambling, and randomization. In backward compatible mode, the device supports up to WXGA and 720p resolutions with 24-bit color depth over a single differential link.

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

TIDA-01453 — 適用於車載資通訊系統車頭元件的 MIPI ® DSI 至 OLDI/LVDS 橋接器參考設計

此參考設計提供了兩種顯示介面選項：一種是帶有 MIPI® DSI 輸出的汽車處理器，另一種是帶有 OpenLDI (OLDI) / LVDS 輸入的汽車資訊娛樂視頻顯示面板。該參考設計提供了兩種變體。設定一將晶片系統 (SoC) DSI 視訊輸出訊號轉換為 OLDI/LVDS 視訊訊號，然後直接連接至整合式顯示器應用的面板上。設定二採用 FPD-Link III SerDes 技術，I²C 透過長纜線將 OLDI/LVDS 視訊訊號及 I²C 控制訊號傳送至面板，以供遠端顯示器應用使用。
