The LMH0031VS/NOPB is a Digital Video Deserializer/Descrambler with video and ancillary data FIFOs is a monolithic integrated circuit that deserializes and decodes SMPTE 292M, 1.485Gbps (or 1.483Gbps) serial component video data, to 20-bit parallel data with a synchronized parallel word-rate clock. It also deserializes and decodes SMPTE 259M, 270Mbps, 360Mbps and SMPTE 344M (proposed) 540Mbps serial component video data, to 10-bit parallel data. Functions performed by the LMH0031 includes clock/data recovery from the serial data, serial-to-parallel data conversion, SMPTE standard data decoding, NRZI-to-NRZ conversion, parallel data clock generation, word framing, CRC and EDH data checking and handling, ancillary data extraction and automatic video format determination. The parallel video output features a variable-depth FIFO which can be adjusted to delay the output data up to 4 parallel data clock periods.
