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. 0m cable length.

2. Equalizer Pathological.

3. Tested on CB1574 board from 5MHz to 2GHz.
