cal sync pulse; a burst gate or back porch clamp pulse; and  
an odd/even output. The odd/even output level identifies  
which video field of an interlaced video source is present at  
the input. The outputs from the LM1881 can be used to  
gen-lock video camera/VTR signals with graphics sources,  
provide identification of video fields for memory storage,  
recover suppressed or contaminated sync signals, and pro-  
vide timing references for the extraction of coded or uncoded  
data on specific video scan lines.  
Application Notes  
The LM1881 is designed to strip the synchronization signals  
from composite video sources that are in, or similar to, the  
N.T.S.C. format. Input signals with positive polarity video  
(increasing signal voltage signifies increasing scene bright-  
ness) from 0.5V (p-p) to 2V (p-p) can be accommodated.  
The LM1881 operates from a single supply voltage between  
5V DC and 12V DC. The only required external components  
besides a power supply decoupling capacitor at pin 8 and a  
set current decoupling capacitor at pin 6, are the composite  
input coupling capacitor at pin 2 and one resistor at pin 6 that  
To better understand the LM1881 timing information and the  
type of signals that are used, refer to Figure 1(a-e) which  
shows a portion of the composite video signal from the end  
of one field through the beginning of the next field.  
sets internal current levels. The resistor on pin 6 (i.e. Rset  
)
allows the LM1881 to be adjusted for source signals with line  
scan frequencies differing from 15.734 kHz. Four major sync  
signals are available from the I/C; composite sync including  
both horizontal and vertical scan timing information; a verti-
