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. Passband ripple is the worst case peak to adjacent valley over a frequency range defined by the measured roll off at the passband edges 5. This is the optimum impedance in order to achieve the performance shown Test Circuit: Actual matching values may vary due to PCB layout and parasitics 12nH 15nH 62 50 18pF 18pF 50 Single-ended 50 1,3,4 5,7,8 Subject to change or obsolescence without notice Rev A 17-Oct-2005 Page 2 of 5
