TEST LEVELS

1. Production test at room temperature and nominal supply voltage with guardbands for supply and temperature ranges.

2. Production test at room temperature and nominal supply voltage with guardbands for supply and temperature ranges using correlated

test.

3. Production test at room temperature and nominal supply voltage.

4. QA sample test.

5. Calculated result based on Level 1, 2, or 3.

6. Not tested. Guaranteed by design simulations.

7. Not tested. Based on characterization of nominal parts.

8. Not tested. Based on existing design/characterization data of similar product.

9. Indirect test.

NOTES:

1. Tested on CB1528 board from 5MHz to 1.435GHz

2. The input coupling capacitor must be set accordingly for lower data rates.
