April 24, 2006 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 0.5VP-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 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 -40В°C to +85В°C …
