Unit

Notes:

1. Analog signal measured as VTIP – VRING. Assumes ideal line impedance matching.

2. The quantization errors inherent in the µ/A-law companding process can generate slightly worse gain tracking

performance in the signal range of 3 to –37 dB for signal frequencies that are integer divisors of the 8 kHz PCM

sampling rate.

3. VDDD, VDDA =3.3 V, VBAT = –52 V, no fuse resistors; RL = 600 , ZS = 600  synthesized using RS register

coefficients.

4. The level of any unwanted tones within the bandwidth of 0 to 4 kHz does not exceed –55 dBm.

5. 0 dBm0 is equal to 0 dBm into 600 .
