In the default jumper connections, both the ADM2582E/ADM2587E driver and receiver are enabled. Figure 2 also shows the power connection on the J2 terminal block, input signal connection on the DI jack, and probes attached to the RXD, DI, Y, and Z test points for a loopback test (LK5 and LK7 are closed to connect A to Y pins and B to Z pins, respectively). The inputs to the ADM2582E/ADM2587E can be configured using the jumpers on the evaluation board (see Table 1). Do not place multiple jumper blocks on the LK1, LK3, and LK6 jumper blocks because the input sources may be shorted together. For each link, a single jumper block can move from one position to another, as specified in Table 1.

Rev. 0 | Page 3 of 12 UG-916 EVAL-ADM2582EEMIZ/EVAL-ADM2587EEMIZ User Guide TERMINATION AND PULL-UP/PULL-DOWN RESISTORS PCB LAYOUT RECCOMENDATIONS The evaluation board includes the RT and RT1 footprints for fitting termination resistors between the A and B receiver inputs and the Y and Z driver outputs. By default, the board is not fitted with a 120 Ω resistor, RT, between A and B. This resistor must be removed if the board is connected to a bus that is already terminated at both ends. For more information about proper termination, see the AN-960 Application Note, RS485/RS-422 Circuit Implementation Guide. Although the ADM2582E/ADM2587E have a built-in receiver fail-safe for the bus idle condition, there are footprints on the evaluation board for fitting the R9 and R10 pull-up resistors to the VISOOUT supply of the ADM2582E/ADM2587E on A and Y, as well as the R7 and R8 pull-down resistors to GND2 on B and Z. These resistors can be fitted if the user is connecting to other devices that require external biasing resistors on the bus. The exact value required for a 200 mV minimum differential voltage in the bus idle condition depends on the supply voltage (for example, 960 Ω for 3.3 V and 1440 Ω for 5 V). For more information about the bus idle fail-safe, see the AN-960 Application Note, RS-485/RS-422 Circuit Implementation Guide. DECOUPLING AND RESERVOIR CAPACITORS The evaluation board uses the following decoupling and reservoir capacitors: • • • • On the logic side of the board, the C3 and C4 capacitors must be 10 nF and 100 nF ceramic capacitors, respectively, and the C2 capacitor must be a 10 µF tantalum capacitor. On the logic side of the board, the C7 capacitor must be a 100 nF ceramic capacitor, and the C9 capacitor must be a 10 µF tantalum capacitor. On the logic side of the board additional capacitors are added for the power regulation circuits. C12, C13, and C16 must be a 10 µF tantalum capacitors, while C14 and C15 must be 100 nF ceramic capacitors. On the bus side of the board, the C5 and C6 capacitors must be 10 nF and 100 nF, respectively, and the C1 and C98 capacitors must be 100 nF and 10 µF, respectively. BOARD INTERNAL LAYER THICKNESS The ADM2582E/ADM2587E evaluation board consists of two layers. The spacing between the top and bottom layer is 1.6 mm. The EVAL-ADM2582EEMIZ and EVAL-ADM2587EEMIZ PCB has a layer spacing of 0.4 mm between Layer 1 and Layer 2, meeting requirements for isolation standards IEC 61010, third edition, and IEC 60950 in the AN-1109 Application Note, Recommendations for Control of Radiated Emissions with iCoupler Devices. The ADM2582E/ADM2587E evaluation board is designed to reduce emissions generated by the high frequency switching elements used by the isoPower technology to transfer power through the ADM2582E/ADM2587E integrated transformer. The layout of the evaluation board is generated using the guidelines provided in the AN-1349 Application Note. The AN-1349 Application Note provides examples of 4-layer PCBs. The EVAL-ADM2582EEMIZ and EVAL-ADM2587EEMIZ PCB layout is a 2-layer PCB. To pass EN55022 Class A on a 2-layer PCB, the following layout guidelines are recommended: • Ensure that there is good decoupling on the PCB (see the Decoupling and Reservoir Capacitors section). • Place a ferrite bead between the PCB trace connections and the following IC pins: VISOOUT (Pin 12) and GND2 (Pin 11 and Pin 14). • Do not connect the VISOOUT pin to a power plane; connect between VISOOUT and VISOIN using a PCB trace. Ensure VISOIN (Pin 19) is connected through the L3 ferrite to VISOOUT (Pin 12) as shown in Figure 3. • Place a high voltage discrete capacitor connected between GND1 (Pin 10) and GND2 (Pin 11).The EVALADM2582EEMIZ requires a high voltage discrete capacitor in order to pass EN 55022 Class A with adequate margin to allow for test variation. However, the EVAL-ADM2587EEMIZ can pass EN 55022 Class A without a high voltage discrete capacitor. Adding a high voltage discrete capacitor to the EVAL-ADM2587EEMIZ allows a larger pass margin from the EN55022 Class A limits. The following additional notes apply to the PCB layout; refer to the schematic and artwork in Figure 10 to Figure 13. • Ensure GND2 (Pin 14) is connected to GND2 (Pin 11) on the inside (device side) of the C1 100 nF capacitor. • Ensure the C1 capacitor is connected between VISOOUT (Pin 12) and GND2 (Pin 11) on the device side of the L2 and L3 ferrites. • Ensure GND2 (Pin 16) is connected to GND2 (Pin 11) on the outside (bus side) of the L2 ferrite as shown in Figure 3. • Ensure that there is a keep out area for the GND2 plane in the PCB layout around the L2 and L3 ferrites. The keep out area means there must not be a GND2 fill on any layer below the L2 and L3 ferrites. • Ensure there is a minimum of 4 mm separation gap between the GND2 plane fill and the GND2 fill for the C19 high voltage discrete capacitor pad.

EN55022 Test Results Summary Device ADM2587E ADM2582E ADM2582E Locate the power delivery circuit in close proximity to the ADM2587E/ADM2582E device, so the VCC trace is as short as possible. The EVAL-ADM2582EEMIZ and EVAL-ADM2587EEMIZ PCB has a power delivery circuit located at the bottom of the PCB with a short trace from the ADP667ARZ regulator output to VCC (Pin 8). This layout example minimizes the loop area in which high frequency current can flow. An increase in the loop area results in an increase in the emissions levels.
