It also deserializes and decodes SMPTE 259M, 270Mbps, 360Mbps and SMPTE 344M (proposed) 540Mbps serial ponent video data, to 10-bit parallel data. Functions performed by the LMH0031 include: 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...
