NOTES
1. TYPICAL - measured on EB-RD35A board, T
A
= 25°C.
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 output from valid re-clocked input data to mute mode when the input signal is removed.
TEST LEVEL
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
10.Production test at room temperature.
