Overview
The DS92LV2412SQ/NOPB, produced by Texas Instruments, is part of the DS92LV241x chipset, which includes the DS92LV2411 serializer and the DS92LV2412 deserializer. This chipset is designed to translate a parallel 24-bit LVCMOS data interface into a single high-speed Current Mode Logic (CML) serial interface with embedded clock information. This design eliminates skew issues between clock and data, reduces connector size, and minimizes interconnect costs for transferring data over FR-4 printed circuit board backplanes, differential or coax cables.
