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 and manufacturing tolerances 4. All attenuation measurements are measured relative to minimum insertion loss 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 22nH 10 5 50 22pF 50 50 Single-ended 1,2,3,4 6,7,8,9 Subject to change or obsolescence without notice Rev - 10-Oct-2005 Page 2 of 5
