Overview: Product Folder Sample & Buy Technical Documents Tools & Software Support & Community THS6226A SBOS643A – APRIL 2014 – REVISED MAY 2014 THS6226A Gated-Class H, Dual-Port VDSL2 Line Driver.

General Description

The THS6226A is a dual-port, class H, currentfeedback architecture, differential line driver amplifier system ideal for xDSL systems.

The device is targeted for use in very-high-bit-rate digital subscriber line 2 (VDSL2) line driver systems that enable native DTM signals while supporting greater than 20.5-dBm line power (up to 8.5 MHz) with good linearity, supporting the G.993.2 VDSL2 8b profile.

The device is also fast enough to support central-office transmissions of 14.5-dBm line power up to 30 MHz.
