Overview
The LMH0341SQ/NOPB is a high-performance SDI Deserializer from Texas Instruments, designed to support various video standards including SMPTE 259M, SMPTE 292M, SMPTE 424M, and DVB-ASI. This device is part of TI’s FPGA-Attach SER/DES product family and is optimized for use with Field-Programmable Gate Arrays (FPGAs). The LMH0341 automatically detects the incoming data rate and decodes the raw 5-bit data words, generating a clean clock and transmitting both clock and data to the host FPGA without the need for external VCOs or clocks.
