DUAL DIFFERENTIAL LINE DRIVERS AND RECEIVERS
SLOS202D– JANUARY 1998– REVISED JULY 1999
APPLICATION INFORMATION
ADSL
The THS6002 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
THS6002 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 59.
