EL1883

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

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.
