The DS92LV0421 and DS92LV0422 enable applications that currently use the popular Channel Link or Channel Link style devices to seamlessly upgrade to an embedded clock interface to reduce interconnect cost or ease design challenges. The parallel LVDS interface also reduces FPGA I/O pins, board trace count and alleviates EMI issues, when compared to traditional single-ended wide bus interfaces. Programmable transmit de-emphasis, receive equalization, on-chip scrambling and DC balancing enables longer distance transmission over lossy cables and backplanes. The Deserializer automatically locks to incoming data without an external reference clock or special sync patterns, providing easy “plug-and-go” operation. The DS92LV0421 and DS92LV0422 are programmable though an I2C interface as well as by pins. A built-in AT-SPEED BIST feature validates link integrity and may be used for system diagnostics. The DS92LV0421 and DS92LV0422 can be used interchangeably with the DS92LV2421 or DS92LV2422. This allows designers the flexibility to connect to the host device and receiving devices with different interface types, LVDS or LVCMOS.

Description: The LV04EVK01 is an evaluation kit designed to demonstrate performance and capabilities of the DS92LV0421 and DS92LV0422 Channel Link II Serializer/Deserializer chipset. The DS92LV0421 serializer board accepts LVDS input signals and provides a single serialized Channel Link II CML data pair as an output. The DS92LV0422 deserializer board accepts the CML serialized data stream and converts the data back into parallel LVDS signals. A USB cable is provided as a generic medium for the high speed data link. Jumpers and switches on the boards can be configured for evaluation of chipset features such as pre-emphasis, equalization, SSCG and backward compatibility. An I2C interface provides an alternative method to configure features of the serializer and deserializer. Contents: One serializer board with the DS92LV0421 One deserializer board with the DS92LV0422 One 2-meter USB 2.0 Hi-SPEED cable assembly Evaluation kit documentation What the user needs to provide A 24-bit data bus and clock source with LVDS outputs - for example a video generator A data error checker or display with LVDS inputs - for example an LCD panel and interface from the deserializer board to the panel itself, or test equipment Power supply for both boards

Note: The Early Failure Rates (EFR) were calculated as point estimate PPM based on rejects and sample size for EFR. The Long Term Failure Rates were calculated at 60% confidence using the Arrhenius equation at 0.7eV activation energy and derating the assumed stress temperature of 150°C to an application temperature of 55°C.
