EL1881
Sync Separator, Low Power
The EL1881 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 resistor 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 vertica...
