Notes:
1. Measured at TIP and RING with 600 Ω. termination at 1 kHz, as shown in Figure 1.
2. Receive full-scale level produces –0.9 dBFS.
3. DR = 20 x log (rms VFS/rms VIN)+ 20 x log (rms VIN/rms noise, excluding harmonics). VFS is the –1 dBm full-scale
level.
4. Measurement is 300 to 3400 Hz. Applies to both transmit and receive paths.
5. VIN = 1 kHz, –3 dBFS
6. THD = 20 x log (rms distortion / rms signal).
7. DRCID = 20 x log (rms VCID/rms VIN)+ 20 x log (rms VIN/rms noise). VCID is the 6 V full-scale level.
