Renesas Electronics Corporation Sync Separator with Horizontal Output EL1883ISZ

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 0.5VsubP-P/sub and 2VsubP-P/sub (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 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 gives horizontal timing with pre/post equalizing pulses.brbr The EL1883 is available in an 8-pin SO package and is specified for operation over the full -40°C to +85°C temperature range.
