ISL59885
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°C to +85°C
temperature range.
