ADSL

The THS6012 was primarily designed as a line driver and line receiver for ADSL (asymmetrical digital subscriber

line). The driver output stage has been sized to provide full ADSL power levels of 20 dBm onto the telephone

lines. Although actual driver output peak voltages and currents vary with each particular ADSL application, the

THS6012 is specified for a minimum full output current of 400 mA at its full output voltage of approximately 12 V.

This performance meets the demanding needs of ADSL at the central office end of the telephone line. A typical

ADSL schematic is shown in Figure 47.
