SBOS416C – OCTOBER 2007 – REVISED APRIL 2009 Dual-Port, Differential VDSL2 Line Driver Amplifiers 23 • Low Power Consumption: The THS6204 is a dual-port, current-feedback architecture, differential line driver amplifier system – 21mA/Port Full Bias Mode ideal for xDSL systems. The device is targeted for – 16.2mA/Port Mid Bias Mode use in VDSL2 (very-high-bit-rate digital subscriber – 11.2mA/Port Low Bias Mode line 2) line driver systems that enable greater than – Low-Power Shutdown Mode +20.5dBm line power up to 8.5MHz with good linearity supporting the G.993.2 VDSL2 8b profile. It – IADJ Pin for Variable Bias is also fast enough to support central-office • Low Noise: transmission of +14.5dBm line power up to – 2.5nV/ √Hz Voltage Noise 18.1MHz—Profile 30a. – 17pA/ √Hz Inverting Current Noise The unique architecture of the THS6204 allows – 1.2pA/ √Hz Noninverting Current Noise quiescent current to be minimal while still achieving very high linearity. Differential distortion, under full • Low MTPR Distortion: bias conditions, is –89dBc at 1MHz and reduces to – 70dB with +20.5dBm G.993.2—Profile 8b only –73dBc at 10MHz. Fixed multiple bias settings of • –89dBc HD3 (1MHz, 100Ω Differential) the amplifiers allows for enhanced power savings for line lengths where the full performance of the • High Output Current: > 424mA (25Ω Load) amplifier is not required. To allow for even more • Wide Output Swing: 43.2V PP (±12V, 100Ω flexibility and power savings, an IADJ pin is available Differential) to further lower the bias currents. • Wide Bandwidth: 150MHz (Gain = 10V/V) The wide output swing of 43.2VPP (100 Ω • Port-To-Port Separation of 90dB at 1MHz differentially) with ±12V power supplies, coupled with over 425mA current drive (25 Ω), allows for wide • PSRR of 50dB at 1MHz for Good Isolation dynamic headroom, keeping distortion minimal. • Wide Power-Supply Range: 10V to 28V The THS6204 is available in a QFN-24 or a TSSOP-24 PowerPAD™ package. • Ideal For VDSL2 Systems • Backward-Compatible with ADSL/ADSL2+/ADSL2++ Systems Figure 1.
