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 will be smaller than the maximum value

specified.

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

3. VDD = 3.3 V, VBAT = –52 V, no fuse resistors, RL = 600 Ω, ZS = 600 Ω synthesized using RS register coefficients.

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

5. The OBIAS and ABIAS registers program the dc bias current through the SLIC in the on-hook transmission and off-

hook active conditions, respectively. This per-pin total current setting should be selected such that it can

accommodate the sum of the metallic and longitudinal currents through each of the TIP and RING leads for a given

application.
