LM1881 Description
Video Sync Separator
LM1881 Vendor
National Semiconductor
LM1881 Categories
Video Sync Separators

LM1881 Features
AC coupled composite input signal
>10 k input resistance
<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)
-40°C to +85°C operation (LM1881-X)

LM1881 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.
