LM1881 Description

The LM1881 Video sync separator extracts timing information including posite and vertical sync, burst or back porch timing, and odd and even field information from standard negative going sync NTSC, PAL (1) and SECAM video signals with amplitude from 0.5-V to 2-V p-p. The integrated circuit is also capable of providing sync separation for nonstandard, faster horizontal rate video signals. The vertical output is...
