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.

EVAL-3CH4CHSOICEBZ Evaluation Board with the iCoupler Digital Isolator Installed Rev. 0 | Page 3 of 10 UG-935 EVAL-3CH4CHSOICEBZ User Guide 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. 16 VDD2 15 GND 2 VIA 3 ENCODE DECODE 14 V OA 4 ENCODE DECODE 13 V OB VOC 5 DECODE ENCODE 12 VIC VOD 6 DECODE ENCODE 11 VID VIB DISABLE1/VE1 7 GND1 8 10 DISABLE2/VE2 9 GND2 3) TERMINAL BLOCK 6) PADS TO CONNECT SMA 4) SHORTING JUMPER 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. Figure 2.

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: • • • • Rev. 0 | Page 4 of 10 A pad layout for a PCB board, edge-mounted SMA connector. 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. A 0603 pad layout between the signal path and VDD1/VDD2 for a pull-up resistor. EVAL-3CH4CHSOICEBZ User Guide • • • UG-935 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. 1 SMA CONNECTOR PADS 2 TERMINATION 3 CONNECT TO SMA 4 PULL-UP 7 LOAD 6 OPEN THROUGH HOLES FOR ACTIVE PROBES GND/GND/SIGNAL 14276-004 5 2-PIN HEADER GND/SIGNAL Figure 4.
