October 31, 2011 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 0.5VP-P
and 2VP-P.
The ISL59885 is available in an 8 Ld SOIC package and is
specified for operation over the full -40В°C to +85В°C
temperature range. Features NTSC, PAL, SECAM, HDTV, Non-standard Video Sync …
