Video Sync Separator
General Description
The LM1881 Video sync separator extracts timing informa-
tion including composite and vertical sync, burst/back porch
timing, and odd/even field information from standard nega-
tive 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.
