Notes:

1. The input signal level should be 0 dBm0 for frequencies greater than 100 Hz. For 100 Hz and below, the level should

be –10 dBm0. The output signal magnitude at any other frequency is smaller than the maximum value specified.

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

3. 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.

4. VDD1–VDD4 = 3.3 V, VBAT = –52 V, no fuse resistors; RL = 600 Ω, ZS =600 Ω synthesized using RS register

coefficients.

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