Texas Instruments THS6301 Line Driver Amplifier
Texas Instruments THS6301 Line Driver Amplifier is a single-channel, current-feedback architecture differential line driver that enables G.Fast and different digital subscriber line (DSL) home gateway systems. The device enables 106MHz and 212MHz G.Fast digital subscriber line profiles that use native discrete multitone modulation (DMT) signals. The THS6301 functions with high linearity at an 8dBm line power through 212MHz.
The unique architecture of this device minimizes quiescent current while providing very high linearity. Internally-fixed bias settings of the amplifier provide power savings for line-driving modes where the full performance of the amplifier is not needed. For further flexibility and power savings, the overall quiescent current is adjustable by a single external bias resistor connected to one of the device pins. The device also features two line-termination modes to maintain impedance matching at very low power consumption.
