Test
Table 7. ac Test Source
1. ac test signal should be ac coupled into TESTSIG.
2. A pull-down resistor to V
REF
should be connected to TESTSIG.
3. This parameter is not tested in production, it is guaranteed by design and characterization.
Table 8. Test Sense
1. This is the voltage coefficient with respect to tip/ring voltage. See Table 20 TESTLEV Output Options (Tip-to-Ring, Tip-to-Ground, and Ring-
to-Ground equations) for application of this parameter.
2. This parameter is not tested in production, it is guaranteed by design and characterization.
