D
1. Measured at TIP and RING with 600 Ω termination at 1 kHz, as shown in Figure 1 on page 5.
2. Receive full scale level produces –0.9 dBFS at DTX.
3. DR = 20 x log |Vin| + 20 x log (rms signal/rms noise). Applies to both transmit and receive paths. Vin = 1 kHz, –3 dBFS.
4. Vin = 1 kHz, –3 dBFS. THD = 20 x log (rms distortion/rms signal).
