Auto-Adjusting Sync Separator for HD

and SD Video

The ISL59885 video sync separator extracts sync timing

information from both standard and non-standard video

inputs in the presence of Macrovision pulses. The ISL59885

provides horizontal, vertical, and composite sync outputs as

well as SD/HDTV detection. An auto input frequency detect

feature automatically adapts to a wide range of video

standards (it does not need a different RSET resistor for

different frequencies). The 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. Fixed 70mV sync tip slicing

provides sync edge detection when the video input level is

between 0.5V

P-P

and 2V

P-P

.

The ISL59885 is available in an 8 Ld SOIC package and is

specified for operation over the full -40擄C to +85擄C

temperature range.
