Check out this complete camera system solution for automotive. The combination of FPD-Link III DS90UB913A / 14A and power components LM34919B-Q1 and LP3907-Q1 provide a solution for a small form factor camera module with minimum footprint power supply requirements and reduced connector count and size by using only a single coax cable for uncompressed megapixel camera data, control signals and power supply.
The DS90UB913A-Q1/DS90UB914A-Q1 chipset offers a FPD-Link III interface with a high-speed forward channel and a bidirectional control channel for data transmission over a single coaxial cable or differential pair. The DS90UB913A-Q1/914A-Q1 chipset incorporates differential signaling on both the high-speed forward channel and bidirectional control channel data paths. The serializer/deserializer pair is targeted for connections between imagers and video processors in an ECU (Electronic Control Unit). This chipset is ideally suited for driving video data requiring up to 12-bit pixel depth plus two synchronization signals along with bidirectional control channel bus.
The deserializer features a multiplexer to allow selection between two input imagers, one active at a time. The primary video transport converts 10-bit or 12-bit data to a single high-speed serial stream, along with a separate low latency bidirectional control channel transport that accepts control information from an I2C port and is independent of video blanking period.
Using TI’s embedded clock technology allows transparent full-duplex communication over a single differential pair, carrying asymmetrical bidirectional control channel information in both directions. This single serial stream simplifies transferring a wide data bus over PCB traces and cable by eliminating the skew problems between parallel data and clock paths. This significantly saves system cost by narrowing data paths that in turn reduce PCB layers, cable width, and connector size and pins. In addition, the Deserializer inputs provide adaptive equalization to compensate for loss from the media over longer distances. Internal DC-balanced encoding/decoding is used to support AC-coupled interconnects. The DS90UB913A-Q1 serializer is offered in a 32-pin WQFN package and the DS90UB914A-Q1 deserializer is offered in a 48-pin WQFN package.
