Industrial field bus isolation
GENERAL DESCRIPTION
The ADuM120N/ADuM121N1 are dual-channel digital isolators
based on Analog Devices, Inc., iCoupler® technology. Combining
high speed, complementary metal-oxide semiconductor (CMOS)
and monolithic air core transformer technology, these isolation
components provide outstanding performance characteristics
superior to alternatives such as optocoupler devices and other
integrated couplers. The maximum propagation delay is 13 ns
with a pulse width distortion of less than 3 ns at 5 V operation.
Channel matching is tight at 3.0 ns maximum.
The ADuM120N/ADuM121N data channels are independent and
are available in a variety of configurations with a withstand voltage
rating of 3 kV rms (see the Ordering Guide). The devices operate
with the supply voltage on either side ranging from 1.8 V to 5 V,
providing compatibility with lower voltage systems as well as
enabling voltage translation functionality across the isolation
barrier.
Unlike other optocoupler alternatives, dc correctness is ensured in
the absence of input logic transitions. Two different fail-safe
options are available in which the outputs transition to a
predetermined state when the input power supply is not
applied or the inputs are disabled.
The ADuM120N0 is pin-compatible with the ADuM1285, and
the ADuM120N1 is pin-compatible with the ADuM1280 and
the ADuM1200. The ADuM121N0 is pin-compatible with
ADuM1286, and the ADuM121N1 is pin-compatible with the
ADuM1281 and the ADuM1201.
Protected by U.S. Patents 5,952,849; 6,873,065; 6,903,578; and 7,075,329. Other patents are pending.

APPLICATIONS INFORMATION
PCB LAYOUT
The ADuM120N/ADuM121N use a high frequency carrier to
transmit data across an isolation barrier using iCoupler chip
scale transformer coils separated by layers of polyimide
isolation. With an on/off keying (OOK) technique and the
differential architecture shown in Figure 13 and Figure 14, the
ADuM120N/ADuM121N have very low propagation delay and
high speed. Internal regulators and input/output design techniques
allow logic and supply voltages over a wide range from 1.7 V to
5.5 V, offering voltage translation of 1.8 V, 2.5 V, 3.3 V, and 5 V
logic. The architecture is designed for high common-mode
transient immunity and high immunity to electrical noise and
magnetic interference. Radiated emissions are minimized with a
spread spectrum OOK carrier and other techniques.
The ADuM120N/ADuM121N digital isolators require no external
interface circuitry for the logic interfaces. Power supply bypassing
is strongly recommended at the input and output supply pins
(see Figure 12). Bypass capacitors are most conveniently connected
between Pin 1 and Pin 4 for VDD1 and between Pin 5 and Pin 8
for VDD2. The recommended bypass capacitor value is between
0.01 µF and 0.1 µF. The total lead length between both ends of
the capacitor and the input power supply pin must not exceed
10 mm.
Figure 13 shows the operation block diagram of a single channel
for the ADuM120N0/ADuM121N0 models, which have the
condition of the fail-safe output state equal to low, where the
carrier waveform is off when the input state is low. If the input
side is off or not operating, the fail-safe output state of low
(noted by the 0 in the model number) sets the output to low.
For the ADuM120N1/ADuM121N1, which have a fail-safe output
state of high, Figure 14 shows the conditions where the carrier
waveform is off when the input state is high. When the input
side is off or not operating, the fail-safe output state of high
(noted by the 1 in the model number) sets the output to high.
See the Ordering Guide for the model numbers that have the
fail-safe output state of low or the fail-safe output state of high.

OVERVIEW
Figure 12. Recommended Printed Circuit Board Layout
In applications involving high common-mode transients, ensure
that board coupling across the isolation barrier is minimized.
Furthermore, design the board layout such that any coupling
that does occur equally affects all pins on a given component
side. Failure to ensure this can cause voltage differentials between
pins exceeding the Absolute Maximum Ratings of the device,
thereby leading to latch-up or permanent damage.
See the AN-1109 Application Note for board layout guidelines.

PROPAGATION DELAY RELATED PARAMETERS
INSULATION LIFETIME
Propagation delay is a parameter that describes the time it takes
a logic signal to propagate through a component. The propagation
delay to a Logic 0 output can differ from the propagation delay
to a Logic 1 output.
All insulation structures eventually break down when subjected
to voltage stress over a sufficiently long period. The rate of
insulation degradation is dependent on the characteristics of
the voltage waveform applied across the insulation as well as on
the materials and material interfaces.

Pulse width distortion is the maximum difference between these
two propagation delay values and is an indication of how
accurately the timing of the input signal is preserved.
Channel matching is the maximum amount the propagation delay
differs between channels within a single ADuM120N/ADuM121N
component.
Propagation delay skew is the maximum amount the propagation
delay differs between multiple ADuM120N/ADuM121N
components operating under the same conditions
JITTER MEASUREMENT
Figure 16 shows the eye diagram for the ADuM120N/ADuM121N.
The measurement was taken using an Agilent 81110A pulse
pattern generator at 150 Mbps with pseudorandom bit sequences
(PRBS) 2(n − 1), n = 14, for 5 V supplies. Jitter was measured
with the Tektronix Model 5104B oscilloscope, 1 GHz, 10 GS/s
with the DPOJET jitter and eye diagram analysis tools. The result
shows a typical measurement on the ADuM120N/ADuM121N
with 380 ps p-p jitter.

The two types of insulation degradation of primary interest are
breakdown along surfaces exposed to the air and insulation wear
out. Surface breakdown is the phenomenon of surface tracking
and the primary determinant of surface creepage requirements
in system level standards. Insulation wear out is the phenomenon
where charge injection or displacement currents inside the
insulation material cause long-term insulation degradation.
Surface Tracking
Surface tracking is addressed in electrical safety standards by
setting a minimum surface creepage based on the working voltage,
the environmental conditions, and the properties of the insulation
material. Safety agencies perform characterization testing on the
surface insulation of components that allows the components to be
categorized in different material groups. Lower material group
ratings are more resistant to surface tracking and, therefore, can
provide adequate lifetime with smaller creepage. The minimum
creepage for a given working voltage and material group is in each
system level standard and is based on the total rms voltage
across the isolation, pollution degree, and material group. The
material group and creepage for the ADuM120N/ADuM121N
isolators are presented in Table 9.
Insulation Wear Out
The lifetime of insulation caused by wear out is determined by
the thickness, material properties, and the voltage stress applied.
It is important to verify that the product lifetime is adequate at
the application working voltage. The working voltage supported
by an isolator for wear out cannot be the same as the working
voltage supported for tracking. It is the working voltage applicable
to tracking that is specified in most standards.
Testing and modeling show that the primary driver of long-term
degradation is displacement current in the polyimide insulation
causing incremental damage. The stress on the insulation can be
broken down into broad categories, such as dc stress, which
causes very little wear out because there is no displacement
current, and an ac component time varying voltage stress,
which causes wear out.

Data Sheet
The ratings in certification documents are usually based on 60 Hz
sinusoidal stress because this the reflects isolation from line
voltage. However, many practical applications have combinations
of 60 Hz ac and dc across the barrier as shown in Equation 1.
Because only the ac portion of the stress causes wear out, the
equation can be rearranged to solve for the ac rms voltage, as is
shown in Equation 2. For insulation wear out with the polyimide
materials used in these products, the ac rms voltage determines
the product lifetime.
VRMS = VAC RMS 2 + VDC 2
(1)
VAC RMS = VRMS 2 − VDC 2
(2)
The working voltage across the barrier from Equation 1 is
VRMS = VAC RMS 2 + VDC 2
VRMS = 240 2 + 400 2
VRMS = 466 V
This is the working voltage used together with the material group
and pollution degree when looking up the creepage required by
a system standard.
To determine if the lifetime is adequate, obtain the time varying
portion of the working voltage. To obtain the ac rms voltage,
use Equation 2.
or
VAC RMS = VRMS 2 − VDC 2
where:
VRMS is the total rms working voltage.
VAC RMS is the time varying portion of the working voltage.
VDC is the dc offset of the working voltage.
VAC RMS = 4662 − 4002
VAC RMS = 240 V rms
In this case, the ac rms voltage is simply the line voltage of
240 V rms. This calculation is more relevant when the waveform is
not sinusoidal. The value is compared to the limits for working
voltage in Table 15 for the expected lifetime, less than a 60 Hz
sine wave, and it is well within the limit for a 50-year service life.
Calculation and Use of Parameters Example
Note that the dc working voltage limit in Table 15 is set by the
creepage of the package as specified in IEC 60664-1. This value
can differ for specific system level standards.

ISOLATION VOLTAGE
The following example frequently arises in power conversion
applications. Assume that the line voltage on one side of the
isolation is 240 VAC RMS and a 400 VDC bus voltage is present on
the other side of the isolation barrier. The isolator material is
polyimide. To establish the critical voltages in determining the
creepage, clearance, and lifetime of a device, see Figure 17 and
the following equations.
