ICS91730
LOW EMI, SPREAD MODULATING, CLOCK GENERATOR
Absolute Maximum Ratings
Stresses above the ratings listed below can cause permanent damage to the ICS91730. 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.

2_{Operating current depends on both the input and output frequencies. The values shown represent the upper and lower}
extremes. The higher the input/output frequency, the higher the current draw. The relationship is linear.
