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 0.5V
P-P
and
-2V
P-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-pin PDIP and SO packages
and is specified for operation over the full -40°C to +85°C
temperature range.

NOTE: Intersil Pb-free products employ special Pb-free material
sets; molding compounds/die attach materials and 100% matte tin
plate termination finish, which is compatible with both SnPb and
Pb-free soldering operations. Intersil Pb-free products are MSL
classified at Pb-free peak reflow temperatures that meet or exceed
the Pb-free requirements of IPC/JEDEC J STD-020C.
