NOTES
1. TYPICAL - measured on characterization board.
2. VDIFF is the differential input signal swing.
3. LOCK is an open collector output and requires an external pullup resistor.
4. If OEM_TEST is permanently enabled, operating temperature range is limited from 0°C to 60°C inclusive.
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.
