The DS92LV042x enables applications currently using popular Channel Link or OpenLDI LVDS style devices to upgrade seamlessly to an embedded clock interface. This serial bus scheme reduces interconnect cost and eases design challenges. The parallel OpenLDI 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 DS92LV0422 automatically locks to incoming data without an external reference clock or special sync patterns, providing easy plug-and-go operation. The DS92LV042x chipset is programmable through an I2C interface as well as through pins. A built-in, atspeed 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.
