The LNS-3901 is a 3G/HD/SD line synchronizer capable of handling hot switches between sources of the same format and phased by less than 10 lines compared to the reference. The output timing can be programmed from ½ to 10½ lines after the 0H of the reference. The reference signal can be an analog blackburst, tri-level sync or the internal URS frame reference signal provided by the REF-1801. The LNS-3901 is a very high density card. Up to 20 cards can fit in a Densité 3 frame.
Supports 3Gb/s level A and level B (dual link)
Automatic detection of video input format
Flexible external reference or internal URS frame reference input
Clean output on video input "hot switches" within a 10-line window
Output timing can be adjusted from ½ to 10½ lines after reference
Automatic passthrough of all ancillary data, VBI and embedded audio
Removes high and low frequency jitter out of the video signal
