NOTES

1. TYPICAL - measured on CB9025A board.

2. Characterized 6 sigma rms.

3. IJT measured with sinusoidal modulation beyond Loop

Bandwidth (at 6.5MHz).

4. Synchronous switching refers to switching the input data from

one source to another source which is at the same data rate (ie.

line 10 switching for component NTSC).

5. Asynchronous switching refers to switching the input data from

one source to another source which is at a different data rate.

6. SDO Mute Time refers to the response of the SDO outputs from

valid re-clocked input data to mute mode when the input signal

is removed.

7. Using the DDI input, A/D=0.

8. Using the SDI input, A/D=1.

9. Carrier detect response time refers to the response of the SSI/CD

output from a logic high to logic low state when the input signal is

removed or its amplitude drops below the threshold set by the

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.
