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_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
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.

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-020B.
