DS90UB913Q/DS90UB914Q PRODUCT BRIEF 10-100MHz 10/12-Bit FPD-Link III SER/DES General Description Features The DS90UB913Q/DS90UB914Q chipset offers a FPD-Link III interface with a high-speed forward channel and a bidirectional control channel for data transmission over a single differential pair. The DS90UB913Q/914Q chipsets incorporate 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. There is a multiplexer at the Deserializer to choose between two input imagers. The Deserializer can have only one active input imager. The primary video transport converts 10/12 bit data over 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 fullduplex 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 Serializer is offered in a 32-pin LLP package and the Deserializer is offered in a 48-pin LLP package.
