Auto-Adjusting Sync Separator for HD
and SD Video
Features
• NTSC, PAL, SECAM, HDTV, non-standard video sync
separation
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
• Fixed 70mV slicing of video input levels from 0.5V
P-P
to
2V
P-P
• Single 3V to 5V supply
• Composite sync output
• Vertical output
when the video input level is between 0.5V
and 2V .
P-P
P-P
• Horizontal output
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.
• HDTV detection
• 81% to 90% Hsync blanking window (R5218)
• Macrovision compatible
• Available in 8 Ld SO package
• Pb-Free plus anneal available (RoHS compliant)
Applications

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.
CAUTION: These devices are sensitive to electrostatic discharge; follow proper IC Handling Procedures.
