GENERAL DESCRIPTION
The EVAL-ADuM3150Z supports the ADuM3150ARSZ and
ADuM3150BRSZ, which are 6-channel SPIsolator® isolators
optimized for use in SPI applications. They include two low
speed channels and a clock delay channel for the implementation
of 40 MHz SPI data transfers. The evaluation board provides a
JEDEC standard, 20-lead SSOP pad layout, support for signal
distribution, loopback, and loads referenced to VDDx or GNDx, as
well as optimal bypass capacitance. Signal sources can be wired
onto the board as well as brought onto the board through edge-
mounted SMA connectors (sold separately) or terminal blocks for
power connections. The board includes 200 mil header positions
for compatibility with Tektronix® active probes.
The EVAL-ADuM3150Z evaluation board can be used to
evaluate the ADuM4150ARIZ and the ADuM4150BRIZ
devices. Although the pad layout on the EVAL-ADuM3150Z
evaluation board does not support the ADuM4150ARIZ and
the ADuM4150BRIZ 20-lead SOIC_IC packages, these devices can
be evaluated with the ADuM3150ARSZ or the ADuM3150BRSZ.
The ADuM4150ARIZ and ADuM3150ARSZ differ by package
and isolation capabilities, but are functionally equivalent for
evaluation. The same is true for the ADuM4150BRIZ and
ADuM3150BRSZ devices.
The board follows best printed circuit board (PCB) design
practices for 4-layer boards, including a full power and
ground plane on each side of the isolation barrier. No other
electromagnetic interference (EMI) or noise mitigation design
features are included on this 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.
For full details, see the ADuM3150 data sheet, which must be
used in conjunction with this user guide when using the EVAL-
ADuM3150Z evaluation board.

EVALUATION BOARD CIRCUITRY
PCB EVALUATION GOALS
The EVAL-ADuM3150Z board is intended to achieve the
following goals:
Evaluate the full range of SPIsolator data transfer
functions.
Power each side of the SPIsolator isolator independently.
Allow high differential voltage to be applied between the
two sides of the SPIsolator isolator.
Allow connecting easily to power, other circuit boards and
instrumentation.
Although the evaluation board comes with the ADuM3150BRSZ
SPIsolator digital isolator installed, the board is also compatible
with the ADuM3150ARSZ.
CONNECTORS
The PCB provides support for three types of interconnections:
SMA edge-mounted connectors.
Through-hole signal ground pairs.
Terminal blocks for power connections.
With these three options, both temporary and permanent
connections to the board can easily be made.
When coaxial connections are desired, SMA connector positions
are available for VDD1 and VDD2 power supplies, as well as all digital
inputs. These SMA connector positions are left unpopulated so
that the user can customize the connectors for a given application.
Pins that are outputs only may not have access to a coaxial
connection. The native output buffers of the ADuM3150 are not
capable of driving a 50  coaxial terminated cable. Bring out
signals leaving the board through the provided through holes or
headers.
Figure 2 shows examples of installed SMA connectors; these
connectors were chosen because they are not only low profile
and provide excellent mechanical connections to the PCB but
also support 50 Ω coaxial cabling. Because most lab equipment is
compatible with BNC connectors, adaptors may be required to
use some on-board connectors.

Figure 2. Optional Components
Power can be connected through the T1 and T2 terminal blocks
or can be wired directly to the PCB via the PR1 and PR2
through-hole positions or the VDD1 and VDD2 SMA
connectors can be populated to connect the coaxial cable. Each
through-hole pair provides a power and ground with the power
on the Pin 1 hole. The pin spacing of each through-hole
connector is 200 mil between centers. This matches the pin
spacing required for Tektronix active scope probes. If a scope
probe connection is desired, the header shown in Figure 2 can
be soldered into the through-hole positions, and the signal pin
can be trimmed to match the height requirements of a
Tektronix active scope probe.
POWER INPUT
Each side of the EVAL-ADuM3150Z SPIsolator isolator requires an
off-board power source. Each power source must be independent if
common-mode voltages are to be applied across the isolation
barrier. Sharing a single supply for both sides of the part across
the isolation barrier does not harm the isolator, and it is useful
for functional testing of the ADuM3150 SPIsolator isolator when
common-mode voltages are not present.
A ground plane and a power plane are present on Layer 2 and
Layer 3 of the PCB on each side of the isolation barrier. Power
connects to the VDD1 and GND1 planes for Side 1 and connects
to the VDD2 and GND2 planes for Side 2.

DATA INPUT/OUTPUT (I/O) STRUCTURES
Each data channel has a variety of structures to help configure,
load, and monitor both the input and output. Figure 3 shows one
of the datapaths from an external connection to the device
under test (DUT) pin. Each channel has the same or a subset of
these connections depending on the particular I/O.
Starting at the external connection, the signal path is
1. Pad layout for a PCB board edge-mounted SMA connector.
2. Two 0805 pads are provided where 100 Ω resistors to
ground can be installed. The combined resistance of 50 Ω
provides a termination for a standard coaxial cable.
3. A 3-pin 100 mil header is provided, where Pin 1 is
connected to ground through a 10 kΩ resistor, and Pin 3 is
connected to VDD through a 10 kΩ resistor. Temporary
pull-up or pull-down can be implemented with a shorting
jumper between Pin 2 and either Pin 1 or Pin 3.
4. A 2-pin 100 mil header provides a signal ground pair that
can be used for clip leads or for shorting a channel to
ground temporarily.
5. 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 a Tektronix active probe, or installing a
2-pin header to allow adjacent channels to temporarily be
shorted together.
Figure 3 shows four 0603 pad layouts between the signal path
and optional connections. Pads with similar functions are
arranged in vertical rows and their function is labeled on the
PCB.
LOAD is a connection to load structures located on the
reverse side of the board. These structures consist of
100 kΩ resistors to power and ground to pull high-Z
outputs to a midrange voltage when not being actively
driven. This is useful during debugging because it allows
easy identification floating outputs. The header and
associated resistors identified in Point 3 are also connected
to the signal path by this pad.
PULL-DOWN is a 0603 pad layout between the signal path
and GND1 or GND2 can be used for installing a permanent
pull-down resistor or load capacitor.
SMA CONNECT is a 0603 pad layout that allows
connection of the datapath to the board edge SMA pad
layout and terminations.
PULL-UP is a 0603 pad layout between the signal path and
VDD1 or VDD2 can be used for installing a permanent pull-up
resistor.
Figure 2 shows many of the optional components installed, as well
as how jumpers can be used to temporarily connect channels.
This figure shows a signal connected to the first channel SMA
and then fanned out to the top three channels and monitored by
an active scope probe.

BYPASS ON THE PCB
Several positions and structures are provided to allow optimum
bypass of the evaluation board. Provisions are made for optional
surface-mount bulk capacitors to be installed near the power
connectors to compensate for long cables to the power supply.
Parallel bypass capacitors are installed near the ADuM3150BRSZ
and consist of a 0.1 µF capacitor for VDD1 on the top side and
bottom side and a 0.1 µF capacitor for VDD2 on the top and
bottom side of the board. It is best to use the top side bypass
positions if possible.
The PCB also implements a distributed capacitive bypass on the
PCB. This consists of power and ground planes closely spaced
on the inner layers of the PCB. This minimizes noise and the
transmission of EMI without using complex design features.
HIGH VOLTAGE CAPABILITY
This PCB is designed in adherence with 3750 V basic insulation
practices. High voltage testing beyond 3750 V is not recommended.
Take appropriate care when using this evaluation board at high
voltages, and do not rely on the PCB for safety functions because it
has not been high potential tested (also known as hipot tested
or dielectric withstanding voltage tested) or certified for safety.
