Texas Instruments THS6226 Dual-Port VDSL2 Line Drivers

Texas Instruments THS6226 Dual-Port
VDSL2 Line Driver

Texas Instruments THS6226 Gated-Class H, Dual-Port VDSL2 Line Driver is a current-feedback architecture, differential line drive amplifier device ideal for xDSL systems. The TI THS6226 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. The TI THS6226 dual-port VDSL2 line driver is also fast enough to support central-office transmission of +14.5dBm line power up to 30MHz. The TI THS6226 line driver is ideal for all VDSL2 profiles and are backwards compatible with ADSL/ADSL2+/ADSL2++ systems. The unique architecture of this TI device allows quiescent current to be minimal while still achieving very high linearity.
