General Description
The EL1881C 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 resis-
tor 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 follow-
ing 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 EL1881C 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 EL1881C is available in the 8-pin PDIP and SO packages and is
specified for operation over the full -40°C to +85°C temperature
range.
