xDSL Differential Line Driver
The ISL1557 is a dual operational amplifier designed for
VDSL2 and ADSL line driving in DMT based solutions. This
device features a high drive capability of 750mA while
consuming only 6mA of supply current per amplifier and
operating from a single 4.5V to 12V supply. The driver achieves
a typical distortion of -80dBc at 150kHz into a 25Ω load.
The ISL1557 is available in the thermally-enhanced 16 Ld QFN
and 10 Ld HMSOP package and is specified for operation
across -40°C to +85°C (IRZ, IUEZ) or -40°C to +125°C (FRZ)
temperature ranges. The ISL1557 has control pins C0 and C1
for controlling the bias and enable/disable of the outputs.
These controls allow for lowering the power to fit the
performance/power ratio for the application.
The ISL1557 is ideal for ADSL2+, SDSL, HDSL2, and VDSL line
driving applications, including both 14.5dBm and 21dBm
applications.

Applications Information
performance of the ISL1557 when operating in the non-inverting
configuration.
Product Description
The ISL1557 is a dual operational amplifier designed for line
driving in DMT ADSL2+ and VDSL solutions. It is a dual current
mode feedback amplifier with low distortion while drawing
moderately low supply current. It is built using the Renesas
proprietary complimentary bipolar process and is offered in
industry standard pinouts. Due to the current feedback
architecture, the ISL1557 closed-loop 3dB bandwidth is
dependent on the value of the feedback resistor. First, select the
desired bandwidth by choosing the feedback resistor, RF, then
set the gain by choosing the gain resistor, RG. The curves at the
beginning of the “Typical Performance Curves” section, on
page 6, show the effect of varying both RF and RG. The 3dB
bandwidth is somewhat dependent on the power supply voltage.
Power Supply Bypassing and Printed Circuit
Board Layout
As with any high frequency device, good printed circuit board
layout is necessary for optimum performance. Ground plane
construction is highly recommended. Lead lengths should be as
short as possible (below 0.25”). The power supply pins must be
well bypassed to reduce the risk of oscillation. A 4.7µF tantalum
capacitor in parallel with a 0.1µF ceramic capacitor is adequate
for each supply pin. During power-up, it is necessary to limit the
slew rate of the rising power supply to within 1V/µs. If the power
supply rising time is undetermined, a series 10Ω resistor on the
power supply line can be used to ensure the proper power supply
rise time.
For good AC performance, parasitic capacitances should be kept
to a minimum, especially at the inverting input. This implies
keeping the ground plane away from this pin. Carbon resistors
are acceptable, but avoid using wire-wound resistors because of
their parasitic inductance. Similarly, capacitors should be low
inductance for best performance.
Capacitance at the Inverting Input
Due to the topology of the current feedback amplifier, stray
capacitance at the inverting input will effect the AC and transient
10k
Feedback Resistor Values
The ISL1557 has been designed and specified with RF = 750Ω
for AV = +5. This value of feedback resistor yields extremely flat
frequency response with 1dB peaking out to 250MHz. As with all
current feedback amplifiers, wider bandwidth, at the expense of
slight peaking, can be obtained by reducing the value of the
feedback resistor. Inversely, larger values of feedback resistor
will cause rolloff to occur at a lower frequency. See the curves in
the “Typical Performance Curves” section, beginning on page 6,
which shows 3dB bandwidth and peaking vs frequency for
various feedback resistors and various supply voltages.
Bandwidth vs Temperature
Whereas many amplifier's supply current and consequently 3dB
bandwidth drop off at high temperature, the ISL1557 is designed
to have little supply current variations with temperature. An
immediate benefit is the 3dB bandwidth does not drop off
drastically with temperature.
Supply Voltage Range
The ISL1557IRZ is designed to operate with supply voltages from
±2.25V to ±6V nominal. Optimum bandwidth, slew rate, and
video characteristics are obtained at higher supply voltages.
Single Supply Operation
If a single supply is desired, values from +4.5V to +12V nominal
can be used as long as the input common mode range is not
exceeded. When using a single supply, be sure to either:
• DC bias the inputs at an appropriate common mode voltage
and AC couple the signal (Figure 25), or:
• Ensure the driving signal is within the common mode range of
the ISL1557. The ISL1557IUEZ must be used in single supply
applications.

100nF 10k
In the inverting gain mode, added capacitance at the inverting
input has little effect because this point is at a virtual ground and
stray capacitance is therefore not “detected” by the amplifier.

ADSL CPE Applications
The ISL1557 is designed as a line driver for ADSL CPE
modems. It is capable of outputting 450mA of output current
with a typical supply voltage headroom of 1.3V. It can achieve
-85dBc of distortion at low 7.1mA of supply current per
amplifier.
line voltage is 1.67VRMS. The ADSL DMT peak to average ratio
(crest factor) of 5.3 implies peak voltage of 7.5V into the line.
Using a differential drive configuration and transformer
coupling with standard back termination, a transformer ratio
of 1:2 is selected. The circuit configuration is shown in
Figure 26.
The average line power requirement for the ADSL CPE
application is 14.5dBm (28mW) into a 100Ω line. The average
