3 Description

The DS90UR910-Q1 is an interface bridge chip that recovers data from the FPD-Link II serial bit stream and converts into a Camera Serial Interface (CSI-2) format compatible with Mobile Industry Processor Interface (MIPI) specifications. It recovers the 24- or 18-bit RGB data and 3 video sync-signals from the serial bit stream compatible to FPD-Link II serializers. The recovered data is packetized and serialized over two data lanes strobed by a half-rate serial clock compliant with the MIPI DPHY and CSI-2 specifications, each running up to 900 Mbps. The FPD-Link II receiver supports pixel clocks of up to
75 MHz. The CSI-2 output serial bus greatly reduces the interconnect and signal count to a graphic processing unit (GPU) and eases system designs for video streams from multiple automotive driver assist cameras.

The DS90UR910-Q1 is available in a 40-pin WQFN package. Electrical performance is qualified for automotive AEC-Q100 grade 2 temperature range
–40°C to 105°C.
