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 I 2C. 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 National’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 LLP package, and Deserializer is offered in a 40-pin LLP package. Applications Industrial Displays, Touch Screens Medical Imaging

Description: The LX16EVK01 is an evaluation kit designed to demonstrate the performance and capabilities of the DS92LX1621 and DS92LX1622 Channel Link III Serializer/Deserializer chipset. The DS92LX1621 serializer board accepts LVCMOS input signals for the high speed forward channel and provides additional LVCMOS I/Os for I2C communication and general purpose control channel signals. A single serialized Channel Link III differential data pair is used for the serial interconnect. The DS92LX1622 deserializer board converts the Channel Link III data stream back into parallel LVCMOS signals and also provides LVCMOS I/Os for I2C communication and general purpose control channel signals. A USB cable is provided as a generic medium for the high speed data link. Contents: One serializer board with the DS92LX1621 One deserializer board with the DS92LX1622 One 2-meter USB 2.0 Hi-SPEED cable assembly Evaluation kit documentation What the user needs to provide: A 16-bit data bus and clock source with LVCMOS outputs - for example a camera sensor A data error checker or display with LVCMOS inputs - for example an LCD panel and interface from the deserializer board to the panel itself, or test equipment An I2C master device Power supply for both boards LV16EVK01 User`s Guide
