1080p Dual FPD-Link III Deserializer

 

Description

The DS90UB940-Q1 is a FPD-Link III Deserializer which, in conjunction with the DS90UB949/947/929-Q1 Serializers, converts 1-lane or 2-lane FPD-Link III streams into a MIPI CSI-2 interface. The Deserializer is capable of operating over cost-effective 50Ω single-ended coaxial or 100Ω 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 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 device automatically detects the FPD-Link III channels and provides 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.
