LM1881

Video Sync Separator

General Description

Features

n AC coupled composite input signal

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,

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.

10 kΩ input resistance

10 mA power supply drain current

n Composite sync and vertical outputs

n Odd/even field output

n Burst gate/back porch output

n Horizontal scan rates to 150 kHz

n Edge triggered vertical output

n Default triggered vertical output for non-standard video

signal (video games-home computers)
