General Description

The LMH0031 SMPTE 292M / 259M 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 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.

Key Features

  • a variabledepth FIFO which can be adjusted to delay the output data up to 4 parallel data clock periods. Ancillary Data may be selectively extracted from the parallel data through the use of masking and control bits in the configuration and control registers and stored in the on-chip FIFO. Reverse LSB dithering is also implemented. The unique multi-functional I/O port of the LMH0031 provides external access to functions and data stored in the configuration and control registers. This feature all.
