The THS6204 is a dual-port, current-feedback architecture, differential line driver amplifier system ideal for xDSL systems. The device is targeted for use in VDSL2 (very-high-bit-rate digital subscriber line 2) line driver systems that enable 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 18.1MHz—Profile 30a.

The unique architecture of the THS6204 allows quiescent current to be minimal while still achieving very high linearity. Differential distortion, under full bias conditions, is -89dBc at 1MHz and reduces to only -73dBc at 10MHz. Fixed multiple bias settings of the amplifiers allows for enhanced power savings for line lengths where the full performance of the amplifier is not required. To allow for even more flexibility and power savings, an I_ADJ pin is available to further lower the bias currents.

The wide output swing of 43.2V_PP (100 differentially) with ±12V power supplies, coupled with over 425mA current drive (25), allows for wide dynamic headroom, keeping distortion minimal.

The THS6204 is available in a QFN-24 or a TSSOP-24 PowerPAD™ package.
