Manufacturer Part Number
ISL59885IS-T13R5218
Description
Auto-Adjusting Sync Separator for HD and SD Video
Manufacturer
INTERSIL [Intersil Corporation]
Datasheet
Auto-Adjusting Sync Separator for HD
and SD Video
The ISL59885 video sync separator is manufactured using
high performance analog CMOS process. This device
extracts ISL59885 sync timing information from both
standard and non-standard video input in the presence of
Macrovision pulses. It provides composite sync, vertical
sync, SD and HDTV detection, and horizontal sync outputs.
Fixed 70mV sync tip slicing provides sync edge detection
when the video input level is between 0.5V
Timing is adjusted automatically for various video standards.
The composite sync output follows 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. ISL59885
has an auto input frequency detect feature that sets the right
timing for any input format.
The ISL59885 is available in an 8 Ld SO package and is
specified for operation over the full -40°C to +85°C
temperature range.
