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 very-high-bit-rate digital subscriber line 2 (VDSL2) line driver systems that enable greater than 14.5-dBm line power, supporting the G.993.2 VDSL2 17a profile. The device is also fast enough to support central-office transmissions of 14.5-dBm line power up to 30 MHz. The device is also targeted for use as a broadband or wideband power line communications (PLC) amplifier for line driver applications.

The unique architecture of the THS6214 uses minimal quiescent current and still achieves very high linearity. Differential distortion, under full bias conditions, is –93 dBc at 1 MHz and reduces to only –73 dBc at 10 MHz. 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. To allow for even more flexibility and power savings, an adjustable current pin (I_ADJ) is available to further lower the bias currents.

The wide output swing of 43.2 V_PP (100-Ω differential load) with ±12-V power supplies, coupled with over 416-mA current drive (25-Ω load), allows for wide dynamic headroom, keeping distortion minimal.

The THS6214 is available in a VQFN-24 or a HTSSOP-24 PowerPAD™ package.
