1. Refer to “AN93: ISOmodem
2. Measured at TIP and RING with 600 termination at 1 kHz, as shown in Figure 1 on page 5.
3. Receive full scale level produces –0.9 dBFS at DTX.
4. DR = 20 x log |Vin| + 20 x log (rms signal/rms noise). Applies to both transmit and receive paths. Vin = 1 kHz, –3 dBFS.
5. Vin = 1 kHz, –3 dBFS. THD = 20 x log (rms distortion/rms signal).
= 3.0 to 3.6 V, TA = 0 to 70 °C for F-grade, Fs = 8 kHz, T
