LM1881 Video Sync Separator February 1995 LM1881 Video Sync Separator General Description The LM1881 Video sync separator extracts timing information including composite and vertical sync burst back porch timing and odd even field information from standard negative going sync NTSC PAL and SECAM video signals with amplitude from 0 5V to 2V p-p The integrated circuit is also capable of providing sync separation for non-standard faster horizontal rate video signals The vertical output is produced on the rising edge of the first serration in the vertical sync period A default vertical output is produced after a time delay if the rising edge mentioned above does not occur within the externally set delay period such as might be the case for a non-standard video signal
