Product Summary
The EL1883ISZ-T7 video sync separator is manufactured using Elantecs high performance analog CMOS process. This EL1883ISZ-T7 extracts sync timing information from both standard and non-standard video input and also in the presence of Macrovision pulses. The EL1883ISZ-T7 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 tip amplitude 143mV to 572mV). A single external resistor sets all internal timing to adjust for various video standards. The composite sync output of the EL1883ISZ-T7 follows video in sync pulses and a vertical sync pulse is output on the rising edge of the first vertical serration following 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 horizontal output of the EL1883ISZ-T7 gives horizontal timing with pre/post equalizing pulses.
