•
数字式可调节静态电流:
9.4mA 至 24.8mA
THS6226A 是一款双端口,H 类,电流反馈架构,差
分线路驱动器放大器系统,此系统非常适合于 xDSL
系统。 该器件旨在应用于超高位速率数字用户线路 2
(VDSL2) 线路驱动器系统,此类系统可启用本地 DTM
信号,同时用良好线性支持高于 20.5dBm 的线路功
率(在高达 8.5MHz 的频率条件下),从而支持
G.993.2 VDSL2 8b 传输模式。 另外,此器件还拥有
足以支持 14.5dBm 线路功率(在高达 30MHz 的频率
下)的中心局传输的高速度。
•
•

(1) The PowerPAD is electrically isolated from all other pins and can be connected to any potential voltage range from VS– to VS+. Typically,
the PowerPAD is connected to the GND plane because this plane tends to physically be the largest and is able to dissipate the most amount
of heat.
(2) The device defaults to the disabled mode at power-up.
(3) Default is GND (internal pull-down resistor).

(1) Stresses above those listed under absolute maximum ratings may cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those indicated under recommended operating
conditions is not implied. Exposure to absolute maximum rated conditions for extended periods may degrade device reliability.
(2) The device incorporates a PowerPAD on the underside of the chip, which functions as a heatsink and must be connected to a thermally
dissipating plane for proper power dissipation. Failure to do so may result in exceeding the maximum junction temperature, which could
permanently damage the device. See the technical brief PowerPAD™ Thermally Enhanced Package (SLMA002) for more information
about using the PowerPAD thermally-enhanced package. Under high-frequency ac operation (> 10 kHz), the short-term output current
capability is much greater than the continuous dc output current rating. This short-term output current rating is roughly 8.5 times the dc
capability, or approximately ±850 mA.
(3) The absolute maximum junction temperature under any condition is limited by the constraints of the silicon process.
(4) The absolute maximum junction temperature for continuous operation is limited by the package constraints. Operation above this
temperature may result in reduced reliability or lifetime of the device.

7 Detailed Description
7.1 Overview
The THS6226A class H line driver provides exceptional ac performance in conjunction with wide output voltage
swing. The class H operation allows voltage swings to exceed the power supply for short intervals limited only by
the charge in the capacitor. In class AB mode, the device is capable of driving a 100-Ω load from +1.8 V to
+10.2 V. In class H mode, under the same conditions, the output voltage range becomes an impressive –5.5 V to
+17.5 V, or 46 VPP differentially with the capacitor fully charged.
The Functional Block Diagram section shows a fully-differential, noninverting amplifier configuration with active
impedance. In this configuration, the 10.2-Ω matching resistor appears through the transformer as 100 Ω,
minimizing reflection on the line. This active impedance scheme also minimizes transmission losses, as
compared to passive termination. Device gain is fixed and is equal to 19 V/V from the input to the output of the
amplifier (INAB/CD to OUTAB/CD), not including the transformer-turn ratio or the termination loss.
To simplify the implementation as well as to provide design flexibility, the device contains an integrated mid-
supply buffer that provides the correct biasing to the amplifier core without requiring any external components.
Also present is a two-pin serial interface that provides exceptional design flexibility and allows minimal power
consumption for each xDSL profile.

7.3 Feature Description
The device incorporates several hardware and functionality features: a high output current line driver, a charge
pump, a voltage reference, a logic circuit, an active impedance, and a RESET pin. The device has two ports.
Each port consists of a high output current line driver, a charge pump, and a reference voltage. Common circuits
are the RESET feature and the logic circuit.
7.3.1 High Output Current Line Driver
The main purpose for the device is to provide a high output current into a heavy load. For the THS6226A, with its
xDSL application targeted, the load is typically 100 Ω and currents as high as 400 mA are supported with
excellent linearity. The core of the line driver is a class AB amplifier providing both good efficiency and high
current drive capability. The high output line driver is the core of the device and any external circuit interface is
located on both the device inputs and output.
7.3.2 Charge Pump
The class H functionality of the device is brought on by the integration of a charge pump. The charge pump is a
power-supply function to the line driver. The role of the charge pump is to vary the power supply from (12 V /
GND) to (20 V / –8 V) and allow the line driver to support high peak to average ratio (PAR) signals while
minimizing power consumption and maintaining excellent linearity. The charge pump is controlled externally by
the VH_EN pin. A logic high on the VH_EN pin results in the power supply of the class AB line driver going to (20 V /
–8 V), while a logic low on the VH_EN pin results in normal operation under the (12 V / GND) supplies.
7.3.3 Voltage Reference
An internal voltage reference provides the device common-mode input and output voltage.
7.3.4 Logic
The DATA and CLK pins allow access to the internal logic circuit implemented in the device. This logic circuit
allows each channel to either be programmed individually for quiescent current, turn the charge pump on or off,
disable the main amplifier, or select the line termination mode. For more information on programming, refer to the
Programming section.
7.3.5 Active Impedance
The line driver incorporates the positive feedback path to provide the termination to the load. For the device, the
synthesis factor implemented is 5.
7.3.6 RESET Pin
The RESET pin provides a quick and easy way to disable the two ports immediately if a fault condition on the
line occurs.
7.4 Device Functional Modes
There are several functional modes for the device. These functional modes can be accessed with the CLK and
DATA pins. Each main line driver quiescent current can be set to 16 different bias modes: bias 0 through bias
15. Additionally, the line driver and class H feature can be controlled to have the following configuration:
•
Class AB mode is the main line driver by itself. The output voltage is limited by the (12 V / GND) power-
supply rails. The quiescent current is then set by four bits.
•
Class H mode is the main line driver used in conjunction with the class H feature. The output voltage is
limited by the (20 V / –8 V) internally-generated power-supply rails. The quiescent current of the main line
driver is set by four bits, as in class AB mode.
•
•
Line termination mode is the powered-down mode for the line driver. This mode maintains line termination but
has reduced linearity performance.
Disabled mode.
For more information on these mode, refer to the Programming section.

7.5 Programming
7.5.1 Programming the Device
Programming the device is accomplished through a serial interface (pins 4 and 5) and proceeds in the following
sequence:
•
•
•
•
Two start bits are required (B0 = 0 followed by B1 = 1).
B2 through B9 are used to program the device. (Table 1 lists the bit descriptions.)
B10 (described in Table 2) is the parity bit that controls whether the word is loaded or not.
B11 is the stop bit and must be set to B11 = 1.
Figure 32 shows the required sequence.

7.5.2 Quiescent Current
The device quiescent current is dissipated in two main device modules: the class AB and the charge pump. Bits
B4 (PD1) and B5 (PD0) select one of the possible four modes of operation:
1. Class AB mode (charge pump disabled),
2. Class H mode (charge pump enabled),
3. Disable mode, or
4. Line termination mode (maintains line matching, core amplifier at very low bias mode and charge pump
disabled for lowest power consumption possible).
Table 3 lists the details on each bit functionality and the approximate quiescent current. The various power
modes are shown in Table 3. For all modes, when B6 through B9 are not defined, set B9 = B8 = B7 = B6 = 0 to
achieve the lowest power dissipation possible.

8 Applications and Implementation
8.1 Application Information
The device is a dual-port, very-high-bit-rate digital subscriber line (VDSL), class H line driver. Typically, the signal
is generated by a high-speed digital-to-analog converter (DAC). The device drives a twisted pair.
The digital subscriber line (DSL) system is ac-coupled as it transmits information above the audio band. On the
input of the line driver, this ac-coupling translates into the series capacitors to isolate the dc voltage coming from
the DAC output common-mode voltage. On the output, a transformer is used to help isolate the 48V present
between tip and ring of the telephone line.
The transformer can be set to any useful ratio. In practice, the transformer-turn ratio is set between 1:1 and 1:1.4
for the device. As mentioned in the Feature Description section, the active impedance synthesis factor is 5. This
synthesis factor means that the termination resistor is 1/5th of the load impedance reflected to the transformer
secondary. Thus, the correct termination can be selected based on the transformer-turn ratio.
Note that the resulting load detected by the amplifier may affect the amplifier linearity or output voltage swing
capabilities.

8.2.2 Detailed Design Procedure
The input capacitor forms a high-pass filter with the device input impedance. This pole must be set at a
frequency low enough to not interfere with the desired signal.
The output transformer can be changed to any transformer-turn ratio. Note that the load is expected to be a
transmission line with 100-Ω characteristic impedance. Referred to the transformer secondary, the load detected
by the amplifier is 1 / n2 with 1:n being the transformer-turn ratio.
Practical limitations force the transformer-turn ratio to be between 1.4:1 and 1:2. At the lighter load detected by
the amplifier (1.4:1), the voltage swing is limited by the class H and the maximum achievable swing of the
amplifier. At the heaviest load (1:2), the voltage swing is limited by the current drive capability of the amplifier. To
satisfy the synthesis impedance factor and the loading, the series resistance (RS) can be set to RS = RL / 5 =
100 Ω / (5 × n2).
For the charge pump, consider the thermal characteristic of the capacitor (X7R, X5R, or Y5V can be used for the
charge pump).
For the power-supply bypass, consider using only X7R or X5R because of the better stability of these materials
over temperature.
For surge protection, consider adding 47-Ω resistors in series on the positive feedback path. The secondary
protection is also normally added after the series resistance on the secondary transformer.

8.3 Initialization Set Up
After the initial power-up and prior to sending any words to program the device, TI recommends sending a string
of twelve 1s (111111111111) to ensure that the state machine is initialized.
9 Power Supply Recommendations
As a result of large recharge current flowing in and out of the four charge pump capacitors during charge pump
discharge and recharge events, TI recommends placing bypass capacitors that are at least equal in value to the
charge pump capacitor close to each supply voltage pin. A minimum of 2-µF bypass capacitors for each channel
are required to minimize any transient appearing on the power supply because both positive and negative charge
pump 1-µF bypass capacitors are recharged on the +12-V supply.

10 Layout
10.1 Layout Guidelines
Achieving optimum performance with a high-frequency amplifier such as the THS6226A requires careful attention
to board layout parasitics and external component types. Recommendations that optimize performance include:
a. Minimize parasitic capacitance to any ac ground for all signal I/O pins. Excessive parasitic capacitance on
the inverting input pin can cause instability. In the line driver application, the parasitic capacitance forms a
pole with the load detected by the amplifier and may reduce the effective bandwidth of the application circuit,
thus leading to degraded performance. To reduce unwanted capacitance, open a window around the signal
I/O pins in all ground and power planes around those pins. Otherwise, make sure that ground and power
planes are unbroken elsewhere on the board.
b. Minimize the distance (< 0.25") from the power-supply pins to high-frequency 0.1-µF decoupling capacitors.
At the device pins, make sure that the ground and power-plane layout are not in close proximity to the signal
I/O pins. Avoid narrow power and ground traces to minimize inductance between the pins and decoupling
capacitors. Always decouple the power-supply connections with these capacitors. An additional low ESR
supply decoupling capacitor (≥ 2 µF, X7R or X5R) to ground is necessary to provide a transient current
during the charge pump capacitors recharge.
c. Careful selection and placement of external components preserves the high-frequency performance
of the device. Use very low reactance type resistors. Surface-mount resistors function best and allow a
tighter overall layout. Metal-film or carbon composition, axially-leaded resistors also provide good high-
frequency performance. Again, keep the leads and printed circuit board traces as short as possible. Never
use wire-wound type resistors in a high-frequency application.
d. Connections to other wideband devices on the board can be made with short, direct traces or through
onboard transmission lines. For short connections, consider the trace and the input to the next device as a
lumped capacitive load. Use relatively wide traces (50 mils to 100 mils), preferably with ground and power
planes opened up around them.
e. Do not socket a high-speed part such as the THS6226A. The additional lead length and pin-to-pin
capacitance introduced by the socket can create an extremely troublesome parasitic network that makes
achieving a smooth, stable frequency response almost impossible. Best results are obtained by soldering the
device onto the board.
