Overview
The DS92LV2412SQE/NOPB is a 24-bit deserializer component produced by Texas Instruments. It is part of the DS92LV2411/12 chipset, which translates a parallel 24-bit LVCMOS data interface into a single high-speed CML serial interface with embedded clock information. This chipset is designed to eliminate skew issues between clock and data, reduce connector size, and lower interconnect costs for transferring data over various mediums such as FR-4 printed circuit board backplanes, differential or coax cables.
The device operates within the industrial temperature range of -40°C to 85°C and is available in a 60-pin WQFN package. It supports application payloads up to 1.2 Gbps and features a 5 to 50 MHz clock range, making it suitable for high-speed data transmission applications.
