Dual port G.Fast and G.mgFast DSL line driver

The THS6302 is a dual port,

current-feedback architecture, differential line driver designed for G.Fast and a

variety of digital subscriber line (DSL) systems. The device is targeted for use in

G.Fast digital subscriber line systems that enable native discrete multitone

modulation (DMT) signals and supports an 8-dBm line power up to 212 MHz with good

linearity.

The unique architecture of this device

allows quiescent current to be minimal and still achieve very high linearity.

Internally-fixed bias settings of the amplifiers offer enhanced power savings for

line-driving modes where the full performance of the amplifier is not required. To

allow for even more flexibility and power savings, the overall quiescent current for

both ports 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.

The THS6302 is a dual port device

suitable for CO (Central Office) applications in DSL systems and is similar to the

single port THS6301 device that is suitable in CPE

(Customer-Premises Equipment) DSL applications.

THS6302 device is available in a 4-mm

× 5-mm, 28-pin, VQFN package.
