Intersil EL1883IS

隔板专业视频NTSC，PAL，SECAM

Overview

The EL1883IS 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 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. The EL1883IS is available in an 8-pin SO package and is specified for operation over the full -40°C to +85°C temperature range.
