描述 Description

The DS90UH947N-Q1 is an OpenLDI to FPD-Link III bridge device which, inconjunction with the FPD-Link III DS90UH940-Q1/DS90UH948-Q1deserializers, provides 1-lane or 2-lane high-speed serial streams over cost-effective 50-Ωsingle-ended coaxial or 100-Ω differential shielded twisted-pair (STP) cables. It serializes anOpenLDI 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 duplexcontrol, including I2C andSPI communication, over the same differential link. Consolidation of video data and controlover 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, andrandomization. In backward compatible mode, the device supports up to WXGA and 720presolutions with 24-bit color depth over a single differential link.
The DS90UH947N-Q1 supports multi-channel audio received through anexternal I2S interface. Audio data received by the device is encrypted and sent over the FPD-LinkIII interface where it is regenerated by the deserializer.
