DS90UB904QSQE/NOPB-10 - 43MHz 18 Bit Color FPD-Link III Deserializer with Bidirectional Control Channel

The DS90UB903Q/DS90UB904Q 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 DS90UB903Q/904Q incorporates differential signaling on both the high-speed forward channel and bidirectional control channel data paths. The Serializer/ Deserializer pair is targeted for direct connections between graphics host controller and displays modules. This chipset is ideally suited for driving video data to displays requiring 18-bit color depth (RGB666 + HS, VS, and DE) along with bidirectional control channel bus. The primary transport converts 21 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. 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 equalization control 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 40-pin lead in WQFN and Deserializer is offered in a 48-pin WQFN packages.
