DS92LX1621 的說明
The DS92LX1621 / DS92LX1622 chipset offers a Channel Link III interface with a high-speed forward channel and a full-duplex back channel for data transmission over a single differential pair. The Serializer/Deserializer pair is targeted for direct connections between automotive camera systems and Host Controller/Electronic Control Unit (ECU). The primary transport sends 16 bits of image data over a single high-speed serial stream together with a low latency bi-directional control channel transport that supports I2C. Included with the 16-bit payload is a selectable data integrity option for CRC (Cyclic Redundancy Check) or parity bit to monitor transmission link errors. Using TI’s embedded clock technology allows transparent full-duplex communication over a single differential pair, carrying asymmetrical bi-directional control information without the dependency of video blanking intervals. 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 sleep function provides a power-savings mode and a remote wake up interrupt for signaling of a remote device.
The Serializer is offered in a 32-pin WQFN package, and Deserializer is offered in a 40-pin WQFN package.
