Notes:
1. Measured at TIP and RING with 600
termination at 1 kHz, as shown in Figure 1 on page 6.
2. With FULL = 1, the transmit and receive full-scale level of +3.2 dBm can be achieved with a 600
ac termination.
While the transmit and receive level in dBm varies with reference impedance, the DAA will transmit and receive 1 dBV
into all reference impedances. With FULL2 = 1, the transmit and receive full-scale level of +6.0 dBm can be achieved
with a 600
termination. In this mode, the DAA will transmit and receive +1.5 dBV into all reference impedances.
3. Receive full-scale level produces –0.9 dBFS at DTX.
4. DR = 20 x log (RMS VFS/RMS Vin) + 20 x log (RMS Vin/RMS noise). The RMS noise measurement excludes
harmonics. Here, VFS is the 0 dBm full-scale level per Note 1 above.
5. Measurement is 300 to 3400 Hz. Applies to both transmit and receive paths.
6. Vin=1kHz, –3dBFS.
7. THD = 20 x log (RMS distortion/RMS signal).
8. DRCID = 20 x log (RMS VCID/RMS VIN) + 20 x log (RMS VIN/RMS noise). VCID is the 1.5 V full-scale level with the
enhanced caller ID circuit. With the typical CID circuit, the VCID full-scale level is 6 V peak, and the DRCID decreases to
50 dB.
9. Refer to Tables 10–11 for relative gain accuracy characteristics (passband ripple).
10. Analog hybrid only. ZACIM controlled by ACIM in Register 30.
