External Components

The ICS581-01 and ICS581-02 require two 0.01

F capacitors between VDD and GND, one on each side of the

chip. These must be close to the chip to minimize lead inductance. Series termination resistors of 33

 should be

used on the outputs, should also be close to the chip, and the feedback path should be a direct connection from a

clock output to a FBIN pin, routed directly under the chip to minimize trace length. This should be connected before

the series termination resistor.

Absolute Maximum Ratings

Stresses above the ratings listed below can cause permanent damage to the ICS581-01/02. 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.
