Table 7. Analog Signal Pins
1. This parameter is not tested in production; it is guaranteed by design and device characterization.
2. VTX offset is measured with respect to pin VRTX.
3. Positive voltages from 0 V to V
CCA
are permitted at input DCR; however, voltages above 0 V have no effect on either the dc feed resis-
tance or tip/ring voltage.
