Overview
The LMH0341SQE/NOPB is a 3G, HD, SD, and 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. It 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. The device features a 5-bit wide LVDS bus, an LVDS clock, and an SMBus interface, eliminating the need for external VCOs or clocks.
