Intersil Introduces Revolutionary HDTV Video Sync Separator

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.

“Existing sync 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."

For the first time, TV and display equipment suppliers have the option to use a single sync processing path that is robust over temperature and tolerant of the variations in broadcast, video and graphics standards worldwide.

ISL59885 Technical Summary
  • NTSC, PAL, SECAM, HDTV, non-standard video support
  • No external set resistors
  • Single 3V to 5V supply
  • Fixed 70mV slicing of video input levels
  • Composite sync output
  • Vertical sync output
  • Horizontal sync output
