Note：
1. All specifications are based on the test circuit shown
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 show
