3 Description
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.
