EL1881
Sync Separator, Low Power
The EL1881 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 EL1881 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 EL1881 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
