Preliminary Information
MH89625C
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 it 0dB; 0dBm0 at the DSTi input will appear as 0dBm at the Tip-Ring output.
Note 2: The receive codec gain is set to 0dB; and the receive gain adjustment is set to 0dB (GS =5V), unless otherwise specified.
Note 3: All dBm is referenced to 600
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.
