Texas Instruments DS90UB633A-Q1 FPD-Link III Serializer

Texas Instruments DS90UB633A-Q1 FPD-Link III Serializer offers an 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 DS90UB633A-Q1 device 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 electronic control unit (ECU). This device is ideally suited for driving video data requiring up to 12-bit pixel depth plus two synchronization signals along with a bidirectional control channel bus.

Using Texas Instrument’s embedded clock technology allows transparent full-duplex communication over a single differential pair, carrying asymmetrical-bidirectional control channel information. 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 feature significantly saves system cost by narrowing data paths that, in turn, reduce PCB layers, cable width, connector size, and pins. Internal DC-balanced encoding/decoding is used to support AC-coupled interconnects.
