Intersil EL1881CSZ-T7

隔板专业视频NTSC，PAL，SECAM

Overview

The EL1881CSZ-T7 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 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 odd/even output indicates field polarity detected during the vertical blanking interval. The EL1881CSZ-T7 is plug-in compatible with the industry-standard LM1881 and can be substituted for that part in 5V applications with lower required supply current. The EL1881CSZ-T7 is available in the 8 Ld PDIP and SOIC packages and is specified for operation over the full -40°C to +85°C temperature range.
