Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the ICS9FG104E. 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.

Input frequency should be measured at the REF pin and tuned to 0 PPM to meet
ppm frequency accuracy on PLL outputs.

These values assume 25MHz or 14.31818MHz inputs respectively. Using a higher or lower frequency will scale
these frequencies accordingly. The output frequecy selected by the FS inputs will also scale. For example, 27MHz
input with an FS selection of 100MHz will yield an output frequency of 27/25 x 100 = 108MHz.
