Notes:

1. All specifications are based on the test circuit shown below

2. In production, devices will be tested at room temperature to a guardbanded specification to ensure electrical compliance over

temperature

3. Electrical margin has been built into the design to account for the variations due to temperature drift and manufacturing tolerances

4. This is the optimum impedance in order to achieve the performance shown
