† AC Gain Electrical Characteristics are over Recommended Operating Conditions unless otherwise stated.

‡ Typical figures are at 25°C with nominal ± 5V supplies and are for design aid only.

x Codec provides adjustment in 1 dB steps.

Note 1: With the transmit gain set to 0dB; 0dBm at the Tip-Ring input will appear as 0dBmO at the DSTo output.

Note 2: The transmit codec gain is set to 0dB unless otherwise specified.

Note 3: All dBm is referenced to 600Ω.

Note 4: Refer to table 2 for control of SLIC gain.

Note 5: Loss Distortion with Frequency is equivalent to the negative of Frequency Response Gain.
