LM1881 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 fast-
er horizontal rate video signals The vertical output is pro-
duced 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 oc-
cur within the externally set delay period such as might be
the case for a non-standard video signal
