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 50Ω single-ended coaxial or
100Ω differential shielded twisted-pair (STP) cables. It serializes
an OpenLDI input supporting video resolutions up to WUXGA and 1080p60 with 24-bit
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
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.
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.
