概要

The 1562B is a very high performance monolithic phaselocked loop (PLL) frequency synthesizer. Utilizing ICS's advanced CMOS mixed-mode technology, the 1562B provides a low cost solution for high-end video clock generation. The 1562B has differential video clock outputs (CLK+ and CLK-) that are compatible with industry standard video DAC. Another clock output, LOAD, is provided whose frequency is derived from the main clock by a programmable divider. An additional clock output is available, LD/N2, which is derived from the LOAD frequency and whose modulus may also be programmed. Operating frequencies are fully programmable with direct control provided for reference divider, prescaler, feedback divider and post-scaler. Reset of the pipeline delay on Brooktree RAMDAC?s may be performed under register control. Outputs may also be set to desired states to facilitate circuit board testing.

  • Two programming options: ICS1562B-001 (Parallel Programming) ICS1562B-201 (Serial Programming)
  • Supports high-resolution graphics - CLK output to 260 MHz, with 400 MHz options available
  • Eliminates need for multiple ECL output crystal oscillators
  • Fully programmable synthesizer capability - not just clock multiplier
  • Circuitry included for reset of Brooktree RAMDAC pipeline delay
  • VRAM shift clock generation capability (-201 option only)
  • External feedback loop capability (-201 option only)
  • Compact - 16-pin 0.150" skinny SOIC package
  • Fully backward compatible to ICS1562

    Parametric Table tips

    Tips for Using This Parametric Table:

    • Hide Filters button in header: Collapse or expands filters
    • Column sort buttons in header: Sort Column alphabetically / numerically descending or ascending
    • Reset button in header: Reset all filters to the page default
    • Full Screen button in header: Expand the table to full screen view (user must close out of full screen before they can interact with rest of page)
    • Export button in header: Export the filtered results of the table to an Excel document
    • Filter parts search bar in header: Type to filter table results by part number
    • Hide column button in column headers: Select to hide columns in table
    • AND / OR toggle switches in header: Toggles the logic of this particular filter to be “AND” or “OR” logic for filtering results
    • Multiselect checkboxes at beginning of each row in table: Select these checkboxes to compare products against each other
    • Document icon next to product name in row: View the featured document for this product
