The test circuit of RS = 1.5 , N = 1, and RL = 30 is equivalent to a standard ADSL circuit with RS = 1.5 , N = 1.8, and RL = 100 .
Output impedance is given by Zo = 10 × RS.
NOTES:
3. Due to the gain of the transmit path, the maximum input voltage should not exceed 3 Vpp or clipping and distortion occurs.
4. A 680-pF input capacitor must be used with the THS7102 to reach the desired HPF response.
