OSCaRTM User Configurable Clock

The dividers are expressed as integers. For example, if a 66.66 MHz output on CLK1 is desired from a

14.31818 MHz input, the VCO divider word (VDW) should be 276, with an output divide (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 divide, use the ICS525 Calculator on our

web site: www.icst.com/products/ics525inputForm.html. The online form is easy to use and quickly shows

you up to three options for these settings. Alternately, you may send an e-mail to ics-mk@icst.com.

Absolute Maximum Ratings

Stresses above the ratings listed below can cause permanent damage to the ICS525-01/02. These ratings,

which are standard values for IDT commercially rated parts, are stress ratings only. Functional operation of

the device at these or any other conditions above those indicated in the operational sections of the

specifications is not implied. Exposure to absolute maximum rating conditions for extended periods can

affect product reliability. Electrical parameters are guaranteed only over the recommended operating

temperature range.
