THS6214,pdf(Dual-Port, Differe

The THS6214 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 +14.5dBm line power, supporting the G.993.2 VDSL2 17a profile. It is also fast enough to support central-office transmissions of +14.5dBm line power up to 30MHz.

The unique architecture of the THS6214 uses minimal quiescent current while still achieving very high linearity. Differential distortion, under full bias conditions, is -93dBc at 1MHz and reduces to only -73dBc at 10MHz. Fixed multiple bias settings of the amplifiers allow for enhanced power savings for line lengths where the full performance of the amplifier is not required.
