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. All parts production tested. In order to guarantee jitter over the

full range of specification (VCC = 3.3V ±5%, TA = 0°C to 70°C,

and 720-880mV launch swing from the SDI cable driver) the

recommended applications circuit must be used.

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

4. Based on characterization data using the recommended

applications circuit , at VCC = 3.3V, TA = 25°C, and 800mV

launch swing from the SDI cable driver.

5. Equalizer Pathological test signal is used.
