Sync Separator with Horizontal Output
The EL1883 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 0.5V
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 EL1883 is available in an 8-pin SO package and is
specified for operation over the full -40°C to +85°C
temperature range.
Ordering Information
NOTE: Intersil Pb-free plus anneal products employ special Pb-free
material sets; molding compounds/die attach materials and 100%
matte tin plate termination finish, which are RoHS compliant and
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-020.
