The THS6022 contains two high-speed drivers

capable of providing 200-mA output current

(minimum) into a 50- Ω load. These drivers can be

configured differentially to drive a 50-V p-p output

signal over low-impedance lines. The drivers are

current feedback amplifiers, designed for the high

slew rates necessary to support low total harmonic

distortion (THD) in xDSL applications. The THS6022

is ideally suited for asymmetrical digital subscriber

line (ADSL) at the remote terminal, high-data-rate

digital subscriber line (HDSL), and very

high-data-rate digital subscribe line (VDSL), where it

supports the high-peak voltage and current

requirements of these applications. Separate power

supply connections for each driver are provided to

minimize crosstalk.

These amplifiers are current feedback topology amplifiers made for high-speed operation. They have been specifically designed to deliver the full power requirements of ADSL and therefore can deliver output currents of at least 200 mA at full output voltage.
PAGE 22
THS6022 www.ti.com SLOS225D – SEPTEMBER 1998 – REVISED JULY 2007 APPLICATION INFORMATION (continued) Power Supply Restrictions Although the THS6022 is specified for operation from power supplies of ±5 V to ±15 V (or singled-ended power supply operation from 10 V to 30 V), and each amplifier has its own power supply pins, several precautions must be taken to assure proper operation. • The power supplies for each amplifier must be the same value.

THS6022 www.ti.com SLOS225D – SEPTEMBER 1998 – REVISED JULY 2007 APPLICATION INFORMATION (continued) The PowerPAD package allows for both assembly and thermal management in one manufacturing operation. During the surface-mount solder operation (when the leads are being soldered), the thermal pad can also be soldered to a copper area underneath the package.

THS6022 www.ti.com SLOS225D – SEPTEMBER 1998 – REVISED JULY 2007 Offset Voltage The output offset voltage, (VOO) is the sum of the input offset voltage (VIO) and both input bias currents (IIB) times the corresponding gains. The following schematic and formula can be used to calculate the output offset voltage: Figure 50. Output Offset Voltage Model Noise Calculations and Noise Figure Noise can cause errors on very small signals. This is especially true for amplifying small signals.

THS6022 www.ti.com SLOS225D – SEPTEMBER 1998 – REVISED JULY 2007 PCB Design Considerations Proper PCB design techniques in two areas are important to assure proper operation of the THS6022. These areas are high-speed layout techniques and thermal-management techniques. Because the THS6022 is a high-speed part, the following guidelines are recommended. • Ground plane—It is essential that a ground plane be used on the board to provide all components with a low-inductance ground connection.
PAGE 29
THS6022 www.ti.com SLOS225D – SEPTEMBER 1998 – REVISED JULY 2007 Because of its power dissipation, proper thermal management of the THS6022 is required. Although there are many ways to properly heatsink this device, the following steps illustrate one recommended approach for a multilayer PCB with an internal ground plane. See Figure 58 for the following steps. Thermal pad area = 150 mils x 170 mils (3.81 mm x 4.32 mm) with 6 vias. Via diameter = 13 mils (0.33 mm). M0089-01 Figure 58.

THS6022 www.ti.com SLOS225D – SEPTEMBER 1998 – REVISED JULY 2007 ADSL The THS6022 was primarily designed as a line driver and line receiver for ADSL (asymmetrical digital subscriber line). The driver output stage has been sized to provide full ADSL power levels of 13 dBm onto the telephone lines.
PAGE 32
THS6022 www.ti.com SLOS225D – SEPTEMBER 1998 – REVISED JULY 2007 The THS6022 has been specifically designed for ultralow distortion by careful circuit implementation and by taking advantage of the superb characteristics of the complementary bipolar process. Driver single-ended distortion measurements are shown in Figure 37 through Figure 40. It is commonly known that in the differential driver configuration, the second-order harmonics tend to cancel out.
PAGE 33
THS6022 www.ti.com SLOS225D – SEPTEMBER 1998 – REVISED JULY 2007 If a multiple-pole filter is required, the use of a Sallen-Key filter can work very well with CFB amplifiers. This is because the filtering elements are not in the negative feedback loop and stability is not compromised. Because of their high slew-rates and high bandwidths, CFB amplifiers can create very accurate signals and help minimize distortion.
PAGE 34
THS6022 www.ti.com SLOS225D – SEPTEMBER 1998 – REVISED JULY 2007 Another good use for the THS6022 amplifiers is as very good video distribution amplifiers. One characteristic of distribution amplifiers is the fact that the differential phase (DP) and the differential gain (DG) are compromised as the number of lines increases and the closed-loop gain increases. Be sure to use termination resistors throughout the distribution system to minimize reflections and capacitive loading.
