The DS92LX2121/DS92LX2122 chipset offers a Channel Link III interface with a high-speed forward channel and a full-duplex control channel for data transmission over a single differential pair. The DS92LX2121/DS92LX2122 incorporates differential signaling on both the high-speed and bi-directional back channel control 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 a bi-directional back channel control bus. The primary transport converts 21 bit data over a single high-speed serial stream, along with a separate low latency bi-directional back 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 bi-directional back channel control 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 cable width, connector size and pins.
In addition, the Deserializer provides input equalization to compensate for loss from the media over longer distances. Internal DC balanced encoding/decoding is used to support AC-Coupled interconnects.
A sleep function provides a power-savings mode when the high speed forward channel and embedded bi-directional control channel are not needed.
The Serializer is offered in a 40-pin lead in WQFN and Deserializer is offered in a 48-pin WQFN packages.
