The dividers are expressed as integers, so that if a 66.66 MHz output is desired from a 14.31818 input, the
Reference Divider Word (RDW) should be 59, and the VCO Divider Word (VDW) should be 276, with
an Output divider (OD) of 2. In this example, R6:R0 is 0111011, V8:V0 is 100010100, and S2:S0 is 001.
Since all of these inputs have pull-up resistors, it is only necessary to ground the zero pins, namely V7, V6,
V5, V3, V1, V0, R6, R2, S2, and S1.
To determine the best combination of VCO, reference, and output divider, use the ICS525 Calculator on
our Web site: http://www.icst.com/wwwcad/ics525inputForm.html. This online form is easy to use and
quickly shows you up to three options for these settings.
