1M pixel ADAS 60-100MHz PCLK serializer

The DS90UB633A-Q1 device

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 bidirectional control

channel bus.

Using TI’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 significantly saves system cost by narrowing data paths that in turn reduce PCB layers, cable width, and connector size and pins. Internal DC-balanced encoding/decoding is used to support AC-coupled interconnects.
