Automatic EDH/CRC Word and Flag  
Processing  
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. 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. 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.
