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. All DC and AC electrical parameters within specification.
2. Set by the value of the RSET resistor.
3. Sum of all 1.8V supplies.
4. Sum of all 3.3V supplies.
