THS6226A Dual-Port VDSL2 Line Driver

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, s.
