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 Features Y Y Y Y Y Y Y Y Y AC coupled composite input signal l 10 kX input resistance k 10 mA power supply drain current Composite sync and vertical outputs Odd even field output Burst gate back porch output Horizontal scan rates to 150 kHz Edge triggered vertical output Default triggered vertical output for non standard video signal video games home computers Connection Diagram LM1881N TL H 9150 1 Order Number LM1881M or LM1881N See NS Package Number M08A or N08E PAL in this datasheet re
