LMH0340, LMH0040, LMH0070, LMH0050 are National's 3 Gbps SDI Serializer and Cable Driver series, supporting 5-bit LVDS interface with FPGAs. These devices comply with DVB-ASI, SMPTE 259M-C, SMPTE 292M and SMPTE 424M standards.
The LMH0340, LMH0040, LMH0070 and LMH0050 are 3 Gbps, HD, SD, DVB‑ASI SDI serializers with integrated LVDS interfaces and cable drivers. They are intended for use with FPGA hosts in digital video signal origination equipment and support SMPTE and DVB‑ASI standards.
The document covers functional description, power‑supply requirements, reset procedures, LVDS input handling, data ordering, PLL loop filter design, DVB‑ASI mode operation, SDI output interfacing, pin‑out tables, absolute maximum ratings, recommended operating conditions, and detailed electrical characteristics.
