The LMH0341/0041/0071/0051 SDI Deserializers are part of TI’s family of FPGA-Attach SER/DES products supporting 5-bit LVDS interfaces with FPGAs. When paired with a host FPGA the LMH0341 automatically detects the incoming data rate and decodes the raw 5-bit data words compliant to any of the following standards: DVB-ASI, SMPTE 259M, SMPTE 292M, or SMPTE 424M. See for details on which Standards are supported per device.

The interface between the LMH0341 and the host FPGA consists of a 5-bit wide LVDS bus, an LVDS clock and an SMBus interface. No external VCOs or clocks are required. The LMH0341 CDR detects the frequency from the incoming data stream, generates a clean clock and transmits both clock and data to the host FPGA. The LMH0341, LMH0041 and LMH0071 include a serial reclocked loopthrough with integrated SMPTE compliant cable driver. Refer to for a complete listing of single channel deserializers offered in this family.

The FPGA-Attach SER/DES product family is supported by a suite of IP which allows the design engineer to quickly develop video applications using the SER/DES products. The product is packaged in a physically small 48 pin WQFN package.
