EL1881C  
Sync Separator, Low Power  
Features  
General Description  
NTSC, PAL, SECAM, non-  
standard video sync separation  
Fixed 70mV slicing of video input  
levels from 0.5VP-P to 2VP-P  
Low supply current - 1.5mA typ.  
Single +5V supply  
Composite, vertical sync output  
Odd/even field output  
Burst/back porch output  
Available in 8-pin PDIP and SO  
The EL1881C video sync separator is manufactured using Elantec’s  
high performance analog CMOS process. This device extracts sync  
timing information from both standard and non-standard video input.  
It provides composite sync, vertical sync, burst/back porch timing, and  
odd/even field detection. Fixed 70mV sync tip slicing provides sync  
edge detection when the video input level is between 0.5VP-P and -  
2VP-P (sync tip amplitude 143mV to 572mV). A single external resis-  
tor sets all internal timing to adjust for various video standards. The  
composite sync output follows video in sync pulses and a vertical sync  
pulse is output on the rising edge of the first vertical serration follow-  
ing the vertical pre-equalizing string. For non-standard vertical inputs,  
a default vertical pulse is output when the vertical signal stays low for  
longer than the vertical sync default delay time. The odd/even output  
indicates field polarity detected during the vertical blanking interval.  
The EL1881C is plug-in compatible with the industry-standard  
LM1881 and can be substituted for that part in 5V applications with  
lower required supply current.
