Product Overview

The LM1881N/NOPB is a video Sync Separator extracts timing information including composite and vertical sync, burst or back porch timing and odd and even field information from standard negative going sync NTSC, PAL and SECAM video signals with amplitude from 0.5V to 2Vp-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.
  • AC Coupled composite input signal

  • Composite sync and vertical outputs
  • Odd and even field output
  • Burst gate or back porch output
  • 150kHz Horizontal scan rate
  • Edge triggered vertical output
  • Default triggered vertical output for non-standard video signal
  • Green product and no Sb/Br
