THS6226 Datasheet Dual-port Vdsl2 Line Driver

Manufacturer: Texas Instruments

Overview: THS6226 www.ti.com SBOS499C – JANUARY 2011 – REVISED APRIL 2011 Gated-Class H, Dual-Port VDSL2 Line Driver Check for Samples:.

General Description

The THS6226 is a dual-port, class H, current-feedback 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 +20.5dBm line power (up to 8.5MHz) with good linearity, supporting the G.993.2 VDSL2 8b profile.

It is also fast enough to support central-office transmission of +14.5dBm line power up to 30MHz.
