EL1883 Sync Separator with Horizontal Output The EL1883 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 and also in the presence of Macrovision pulses.

It provides composite sync, vertical sync, burst/back porch timing, and horizontal outputs.

Fixed 70mV sync tip slicing provides sync edge detection when the video input level is between 0.5VP-P and 2VP-P (sync
