MILPITAS, CA – Intersil Corporation (NASDAQ: ISIL), a world leader in the design and
manufacture of high performance analog solutions, today announced the release of the ISL59885, a new sync separator
that extracts sync timing information from both standard and non-standard video inputs. This timing information is
critical to the detection and alignment of different formats on a screen. The ISL59885 provides support for HDTV and
standard definition formats.
The ISL59885 provides composite sync, horizontal sync and vertical sync outputs.
It requires no external programming or set resistors. This allows maximum system flexibility since it does not
require an external microprocessor or manual configuration. Additionally, high definition video is flagged by the HD
pin going low when the input horizontal frequency is greater than 20KHz.
For the first
time, TV and display equipment suppliers have the option
to use a single sync processing path that is robust over
and tolerant of the variations in broadcast, video and graphics
separator architectures require significant involvement of the rest of the system to adjust the timing based on the
incoming line rate," said Sameer Vuyyuru, Intersil's director for High Speed Analog. "Our new ISL59885 eliminates
that requirement by using a revolutionary frequency to current converter that auto calibrates the timing of the
device. The device also includes a system power saving feature called HD Detect that allows the system designer to
control the scaler parameters."
