Using the EVAL-3CH4CHSOICEBZ iCoupler Data Isolator Evaluation Board
FEATURES
GENERAL DESCRIPTION
Access to all 4 data channels
Enable/disable controls
Multiple connection options
Support for active probes
Provision for cable terminations
Support for PCB edge-mounted coaxial connectors
Easy configuration
Sample iCoupler digital isolator must be ordered separately
The EVAL-3CH4CHSOICEBZ evaluation board supports tripleand quad-channel standard data isolators in 16-lead SOIC
packages. The evaluation board provides a JEDEC standard
16-lead SOIC_N and SOIC_W pad layout and routing appropriate
for the evaluation of supported devices. The evaluation board
provides a connection to power supplies by screw terminals and
includes optimal bypass capacitors. Signal channel routing supports
signal distribution, loopback, and provides positions for loads
referenced to the VDD1/VDD2 and GND1/GND2 planes. Signal
sources can be conducted to the board through header pins or
edge-mounted SMA connectors; SMA connectors must be ordered
separately. Positions for through-hole 0.2 inch headers compatible
with active probes are provided on the printed circuit board (PCB);
probe header pins must be ordered separately.

PLEASE SEE THE LAST PAGE FOR AN IMPORTANT
WARNING AND LEGAL TERMS AND CONDITIONS.
The board follows PCB design practices for 4-layer boards,
including a full power and ground plane on each side of the
isolation barrier. No other EMI or noise mitigation design
features are included on the board. In cases of very high speed
operation or when ultralow emissions are required, refer to the
AN-1109 application note for additional board layout techniques.
Full specifications for the device under test (DUT) are available in
the corresponding product data sheet, which should be consulted
in conjunction with this user guide when using the
evaluation board.

EVALUATION BOARD CIRCUITRY
PCB EVALUATION FUNCTIONS
The EVAL-3CH4CHSOICEBZ board evaluates the full range of
iCoupler® data transfer functions, powers each side of the
iCoupler isolator independently, and applies high differential
voltages between the two sides of the isolator. The board is
intended for evaluation of the components, but has not been
safety certified for high voltage operation. If differential voltages
above 60 V are applied, external safety measures appropriate for
the voltage must be in place.

Figure 3. Optional Components
Power can be connected through the J1 and J2 (Terminal 1 power,
Terminal 2, and GND, as marked on silkscreen) terminal blocks or
the optional VDD1 and VDD2 SMA connectors. Signals can be
routed in or out of the board with the provided header pins or
optional SMA connectors. The pin spacing of each through-hole
connector is 0.1 inch between centers. There are additional signal
test points with 0.2 inch spacing provided for active scope
probes. These header pins must be added separately. Installed
probe points are shown in Figure 3.
Each side of the iCoupler standard data isolator requires an offboard power source. The power source must be independent if
common-mode voltages are applied across the isolation barrier
or damage may occur to the power supply.

The evaluation board comes with power terminals, bypass
capacitors, and header pins installed. The compatible iCoupler
digital isolator must be ordered and installed separately. The
EVAL-3CH4CHSOICEBZ is compatible with triple- and quadchannel iCoupler standard data isolator devices, including the onoff keying architecture devices such as the ADuM130D/
ADuM130E/ADuM131D/ADuM131E and ADuM140D/
ADuM140E/ADuM141D/ADuM141E/ADuM142D/ADuM142E
in 16-lead SOIC_W and 16-lead SOIC_N packages. Figure 2
shows a general footprint of a supported device, showing the data
channel, power, and ground pins.
1) SCOPE PROBE
SMA edge-mounted connectors
Through-hole signal ground pairs
Terminal blocks for power connections
Divided power and ground planes are present on Layer 2 and
Layer 3 of the PCB on each side of the isolation barrier shown
in Figure 7 and Figure 8. Power connects to VDD1 for Side 1
and to VDD2 for Side 2.
DATA INPUT/OUTPUT STRUCTURES
With these three options, it is possible to make temporary and
permanent connections to the board.
When coaxial connections are required, SMA connector positions
are available for digital input and output signals and VDD1 and
VDD2 power supplies. The SMA connector positions must be
ordered from a distributor separately. Figure 3 shows examples of
installed SMA connectors; these connectors are not only low
profile and provide excellent mechanical connections to the
PCB but also support 50 Ω coaxial cabling.
Each data channel has a variety of structures to configure, load,
and monitor both the input and output. Figure 4 shows an example
of the routing from an external connection to a DUT data
channel. Each data channel has similar connections available.
Starting at the external connection, the signal path is
constructed as follows:

Two 0805 pads are provided where 100 Ω resistors to
ground can be installed. The combined resistance is 50 Ω
to provide a termination for a standard coaxial cable.
A standard 0805 pad layout where the coaxial and termination
structures can connect to the rest of the signal path.

VDD1/VDD2 for a pull-up resistor.

A populated 2-pin header provides a signal ground pair
that can be used for clip leads or shorting a channel to
ground temporarily.
There are groupings of three open through holes, consisting
of a signal and two ground connections. These holes can be
used for hardwiring signal wires into the PCB, installing a
header to accept an active probe, or installing a 2-pin header
to allow adjacent channels to temporarily be shorted together.
A 0805 pad layout between the signal and ground where a
load capacitor or resistor can be installed.
Figure 3 shows many of the optional components installed as well
as how jumpers can temporarily connect channels. The figure
shows a signal connecting to the first-channel SMA and fanning
out to the top three channels, monitored by an active scope probe.
BYPASS ON THE PCB
Optional surface-mount bulk capacitors, C1 and C14, are
installed near the power connectors compensate for long cables
to the power supply. Bypass capacitors, C7 and C8, are installed
near the iCoupler isolator and consist of a 0.1 µF capacitor for
both DUT power supply pins.
The PCB also implements a distributed capacitive bypass. The
capacitive structure consists of power and ground planes spaced
closely on the inner layers of the PCB. This minimizes noise
and the transmission of electromagnetic interference (EMI)
without using complex design features.
HIGH VOLTAGE CAPABILITY
The PCB is designed in adherence with 2500 V basic insulation
practices. High voltage testing beyond 2500 V is not recommended.
The evaluation board must not be relied on for safety functions.
