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 res.
