The DS90UB940-Q1 is a FPD-Link III deserializer which, together with the
DS90UH949/947/929-Q1 serializers, converts 1-lane or 2-lane FPD-Link III streams into a
MIPI® CSI-2 format. The deserializer can operate over cost-effective
50-Ω single-ended coaxial or 100-Ω differential shielded twisted-pair (STP) cables. It recovers the
data from one or two FPD-Link III serial streams and translates it into a camera serial interface
(CSI-2) format that can support 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 decreases 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 device automatically senses the FPD-Link III channels and supplies a clock alignment
and de-skew functionality without the need for any special training patterns. This ensures skew
phase tolerance from mismatches in interconnect wires such as PCB trace routing, cable pair-to-pair
length differences, and connector imbalances.
