All specifications are based on the test circuit shown below
In production, devices will be tested at room temperature to a guardbanded specification to ensure electrical compliance over
temperature
Electrical margin has been built into the design to account for the variations due to temperature drift and manufacturing tolerances
Passband ripple is defined as the worst-case peak to adjacent valley with in the passband. The edge of the passband is the point
where the amplitude begins a downward trend that does not reverse until the stopband.
Stopband rejection is measured with reference to the insertion loss at F
O
This is the optimum impedance in order to achieve the performance shown

Actual matching values may vary due to PCB layout and parasitics
