PAD LAYOUT FOR THE DUT
U1
The evaluation board has a pad layout in U2 that accommodates SOP16 wide body devices as shown in Figure 2. Power
and ground connections connect to capacitor pads for Side 1
and Side 2.

Figure 3. ADuM5000 Pad Layout Component U1
Figure 2. DUT Pad Layout Component U2
Three low inductance, surface-mount bypass capacitors are
provided for each side. A 100 nF capacitor is installed on each
side in Capacitor C2 and Capacitor C3.
In addition, there are 10 μF ceramic X7R capacitors, C1 on Side 1
and C4 on Side 2, that provide high frequency bypassing and
ripple reduction. For further ripple reduction in isoPower™
devices like the ADuM540x, tantalum capacitors are added to
C10 as a 68 μF value on Side 1 and to C5 as a 22 μF value on
Side 2. These large value ceramic and tantalum bypass
capacitors are not necessary for non-isoPower devices.
Many of the iCoupler devices have configuration pins that allow
outputs to be disabled or default levels to be set. These pins are
usually located at Pin 7 and Pin 10 in the wide body package.
Pull-up 0 Ω resistors on SM Pad R4 and and SM Pad R17 have
been provided to pull these pins high. If desired, these pull-up
resistors can be removed and pull-down resistors can be
installed on R5 and R18.
In addition to the U2 DUT space, an additional pad layout is
provided at U1, specifically to accommodate another isoPower
device, as shown in Figure 3. This is a power supply only device
that can be used to provide secondary power for any iCoupler,
in standalone mode or as a slave, to boost power to the
ADuM540x or ADuM520x devices. The surface-mount resistor
pads to control these functions are not populated.
Grounding Scheme
The board consists of two separate ground and power systems.
Each side of the DUT can be operated from an independent
power and ground reference. This allows simulation of
conditions similar to the target application. The board provides
for board creepage and clearance typical of most 2.5 kV circuit
boards. It is not recommended for use above 2.5 kV rms transient
voltages.
EMI and EMC Measurements
The signal path has been made as simple as possible while still
providing flexibility. The board is not intended for detailed
characterization of system noise, EMI, or EMC. It may be useful
for initial bench work in these areas, but Analog Devices, Inc.,
does not guarantee that board results will be indicative of the
final system performance in these areas.
TERMINALS
Side 1 Power Supply Inputs
Power is supplied to the board via a set of terminal block
connectors labeled IO_1C, as shown in Figure 4. Power is
connected to the top terminal Pin 1, and ground is connected to
the top terminal Pin 2. Provisions for adding in line inductors
for noise isolation have been made with the inclusion of Z1 and
Z2, which are 1206 size surface-mount components. These
positions are populated with 0 Ω resistors to connect power to
the board. If isolation inductors are required, these components
should be removed and replaced at your discretion.
Pad layout for the ADuM5000 is provided in U1, but this part is
not populated. As can be seen in Figure 3, the power and ground
connections for this device are different from the rest of the
iCoupler components. Bypass capacitor Pad C6 through Pad C9
are provided but not populated (0.1 μF X7R ceramic capacitors
are recommended). Pull-up, pull-down, and connecting resistor
pads are provided (but not populated) to connect the ADuM5000
in master or slave mode, as well as to set the output voltage.

Figure 5. Side 2 Terminal Block Connector
Figure 4. Side 1 Terminal Block Connector
The power and ground from the screw terminal block are
connected to the Side 1 power and ground pads of the DUT and
provide power and ground to pull-up and pull-down resistors
and terminations.
Side 2 Power Supply Connections
The Side 2 connections are different from those on Side 1. With
standard iCoupler devices, these connections are power supply
inputs for Side 2. However, with isoPower devices such as the
ADuM540x, these same connections can be power outputs for
off-board circuits. In addition, they can be configured as an
independent power supply for the project area.
Power is connected to the terminal block connector labeled
IO_1D, as shown in Figure 5. Power is connected to the top
Pin 1, and ground is connected to Pin 2. Provisions for adding
in line inductors for noise isolation or for isolating the jacks
from the on board power connections have been made with the
inclusion of Z6 and Z7. These positions are populated with 0 Ω
resistors to connect power from the ADuM540x to the IO_1D
terminal block.
When standard iCoupler isolators are installed, the Z6 and Z7
pads should be populated with 0 Ω resistors to connect the
power jacks to the power pins of the DUT. Inductors can be
installed if noise isolation is required.
When isoPower devices are installed on the board, the power
configuration required can vary greatly, depending on the
demands of the application. With 0 Ω resistors or inductors
installed at Z6 and Z7, the power jacks can provide power from
the isoPower device to an external device.
With Z6 and Z7 open, IO_1D Pin 1 and Pin 2 become generalpurpose connections that can be wired into the project area
with the through hole connections provided. Without Z6 and
Z7 populated, these pins then become completely isolated from
the ground and power connections on the board (see the complete
schematic shown in Figure 7).

DATA I/O CONNECTIONS
DESIGN AREA
Side 1 Data I/O
The design area of the evaluation board is provided to allow
bread-boarding of application components such as RS485 and
CAN transceivers, ADC or DAC components with direct
interconnects. The design area, as shown in Figure 6, accepts
most surface-mount narrow and wide body components with
50 mil and 100 mil pitch, as well as narrow and wide body
300 mil DIP through hole devices. These surface-mount discrete
components and jumper wires can be used to complete a wide
variety of circuits.
Signals can be provided to the board and routed to the required
input pins through the IO_1C terminal block connector, as
shown in Figure 4. Four channel inputs/outputs can be connected
through IO_1C Pins 3 through Pin 6 to the respective A, B, C,
and D channels of the ADuM540x.
Signals from the IO_1C terminal block connector channels can
also be routed to some of the other data lines through the JP1A
and JP1B jumper blocks (these jumper blocks also correspond
to BNC Channel A and Channel B, if you populate them). Each
jumper block allows a channel signal from the terminal block
IO_1C to be connected to additional data input lines by
configuring the jumpers. The jumper blocks can also be used to
wrap signals from an iCoupler output back to an input by using
the JP1A or JP1B block to cross connect inputs and outputs.
The design area has convenient connection points to the
primary data path CHA to CHD of the iCoupler, as well as
power connections for VISO and GNDISO. To allow signals from
the design area to be routed to the IO_1D terminal block, you
should remove the R23 0 Ω through R26 0 Ω resistors. Note
that no ground plane is provided in the design area.
A common way to provide signals is with a function generator
through 50 Ω coax cables. The ADuM540x board has a layout
position at IO_1A and IO_1B for adding two BNC connectors,
but these are not provided with the board. You can purchase the
coax cables (AMP #227699-2) and populate these BNC
connectors. In addition, to have 50 Ω terminations on the board
for the added BNC connectors, a 50 Ω through hole resistor
must be added at the R1 and R2 positions. It is possible to route
data outputs to this connector as well, but it is not recommended
because proper termination is not possible for logic level signals,
and improper termination can cause severe ringing on the
output lines.
Also part of the Side 1 I/O structure are the pull-up/pull-down
load positions R7 through R14. Discrete through hole resistors
and capacitors can be installed at these positions to simulate
most loading conditions or to provide pull-ups for open
collector outputs.

Signals can be provided to the board and routed to the required
input pins through the IO_1D terminal block connector, as
shown in Figure 5. It consists of terminal block connections that
operate like the Side 1 structures. The terminal block connections
can also be used to wrap signals from an iCoupler output back
to an input.
