3 Description
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
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.
