Overview
The LMH0341SQX/NOPB is a 3G HD/SD DVB-ASI SDI deserializer produced by Texas Instruments. This component is part of TI’s family of FPGA-Attach SER/DES products, designed to support 5-bit LVDS interfaces with FPGAs. The LMH0341 automatically detects the incoming data rate and decodes the raw 5-bit data words compliant with standards such as DVB-ASI, SMPTE 259M, SMPTE 292M, and SMPTE 424M. It features a compact 48-pin WQFN package and operates within an industrial temperature range of -40°C to +85°C.
