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)  
• 70% to 90% Hsync blanking window (R5260)  
• Macrovision compatible  
• Available in 8 Ld SO package  
• Pb-Free plus anneal available (RoHS compliant)  
Applications  
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.  
• High definition video equipment
