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. The input coupling capacitor must be set accordingly for lower

data rates.

2. This parameter applies only to the GS1528A.

3. Rise/Fall time measured between 20% and 80%.
