Exposure to maximum rating conditions for extended periods may reduce device reliability. There is no damage to device with only one parameter set at the limit and all other
parameters set at or below their nominal value. Exceeding any of the limits listed here may result in permanent damage to the device.
CAUTION:
Although this device is designed to be as robust as possible, Electrostatic Discharge (ESD) can damage this device. This device
must be protected at all times from ESD. Static charges may easily produce potentials of several kilovolts on the human body
or equipment, which can discharge without detection. Industry-standard ESD precautions should be used at all times.

Evaluation Board Description
The SKY12322-86LF Evaluation Board is used to test the
performance of the SKY12322-86LF digital attenuator. An
assembly drawing for the Evaluation Board is shown in Figure 7
and an Evaluation Board schematic diagram is shown in Figure 8.
Package and Handling Information
Instructions on the shipping container label regarding exposure to
moisture after the container seal is broken must be followed.
Otherwise, problems related to moisture absorption may occur
when the part is subjected to high temperature during solder
assembly.
THE SKY12322-86LF is rated to Moisture Sensitivity Level 1
(MSL1) at 260
°C.
It can be used for lead or lead-free soldering.
For additional information, refer to the Skyworks Application Note,
Solder Reflow Information,
document number 200164.
Care must be taken when attaching this product, whether it is
done manually or in a production solder reflow environment.
Production quantities of this product are shipped in a standard
tape and reel format.
Package Dimensions
