Dual line driver/receiver
This 200-MHz device can be used to design a wide range of communications systems, but it is particularly well suited to asymmetrical digital subscriber line (ADSL) applications, including central office switches and multiplexers. It is part of TI's newly introduced ADSL chipset (See ADSL article), which features an advanced programmable DSP, digital interface and analog front end. The new line driver/receiver features four amplifiers Ñ two designed to perform the task of line drivers, while the other two feature the performance characteristics of receivers. All four amplifiers carry a slew rate of 1,000 volts per microsecond, assuring very low levels of total harmonic distortion (THD). A high slew rate minimizes distortion by allowing the output of a line driver/receiver to follow more closely the rise and fall of the input signal. The THS6002's output drive of more than 400 milli-amps is ideal for driving low-impedance lines the two to three miles required by the telephone network's local loop. The THS6002 is expected to be available during the first half of 1998 from TI and authorized distributors.
