7.1 Overview

The THS6301 is a current-feedback architecture, differential line driver designed for G.Fast and xDSL systems. The device is targeted for use in G.Fast digital subscriber line (DSL) systems that enable native discrete multitone modulation (DMT) signals and supports an 8-dBm line power up to 212 MHz with good linearity.

The device consists of a unique architecture consisting of an amplifier in a noninverting configuration with an internally-fixed gain of 8.5 V/V. The THS6301 is designed to drive the high-performance G.Fast 212-MHz DSL profile, but is also backwards-compatible to drive lower frequency profiles. The device features selectable bias modes for the G.Fast 106-MHz profile, VDSL profiles, and ADSL profiles. These modes reduce the quiescent current of the device based on the frequency requirements of the various DSL profiles to maximize power efficiency. Along with adjustable bias modes, the device features two line-termination modes that maintain an output impedance match with low power consumption. The line-termination modes allow for the device to be in a low-power state without causing distortion on a shared signal line.

For further flexibility, the THS6301 features an IADJ pin that is used to further adjust the quiescent current of the device. A resistor connected to this pin can be changed to increase or decrease the device current to meet performance requirements and uses the lowest amount of power possible.
