LMH0031 is a deserializer and decoder produced by Texas Instruments. It can decode SMPTE 292M, 259M, 344M and other standard video data, and convert them into 20-bit or 10-bit parallel data.
The LMH0031 is a monolithic integrated circuit that deserializes and decodes SMPTE 292M, 259M and 344M serial component video streams to parallel data. It includes clock/data recovery, NRZI‑to‑NRZ conversion, built‑in self‑test (BIST), a video test pattern generator, and an adjustable FIFO for video and ancillary data.
The device is supplied in a 64‑pin TQFP package, operates from a +2.5 V core supply and a +3.3 V I/O supply, and typically dissipates 850 mW. It supports data rates from 270 Mbps up to 1.485 Gbps and offers flexible control via a multi‑function I/O port.
