The evaluation board allows all of the input and output functions to be exercised without the need for external components. Screw terminal blocks provide convenient connections for logic signals and power. The main device on the evaluation board, the ADM3054, is a controller area network (CAN) physical layer transceiver with integrated digital isolation, allowing a protocol layer CAN controller to access the physical layer bus. The ADM3054 complies with the ISO 11898 standard. It is capable of running at data rates of up to 1 Mbps. The evaluation board has separate ground and power planes for the logic side and the bus side. This allows evaluation of the isolation capability of the ADM3054, which employs Analog Devices, Inc., iCoupler® technology to combine a 3-channel isolator and a CAN transceiver into a single, 16-lead wide body SOIC package. APPLICATIONS ADM3054 part evaluation Evaluation connected to existing CAN controllers/data buses EVALUATION KIT CONTENTS EVAL-ADM3054EBZ The power is isolated between a single 3.3 V or 5 V supply on VDD1, the logic side, and a single 5 V supply provided on VDD2, the bus side. Loss of power on the bus side (VDD2) can be detected by an integrated VDD2SENSE signal. 10397-001 EVAL-ADM3054EBZ Figure 1.

Connect the oscilloscope probes to the CANH and CANL test points. A plot of the oscilloscope for TXD, RXD, CANH, and CANL is shown in Figure 2. Channel 1 shows the TXD signal, Channel 2 and Channel 3 show the CANH and CANL signals, respectively, and Channel 4 shows the RXD signal. The EVAL-ADM3054EBZ allows the ADM3054 isolated CAN transceiver to be quickly and easily evaluated. The evaluation board allows all of the input and output functions to be exercised without the need for external components. On the EVAL-ADM3054EBZ, the power is isolated between a single 3.3 V or 5 V supply on VDD1, the logic side, and a single 5 V supply provided on VDD2, the bus side. When the part is in recessive mode and actively switching states at 1 Mbps, the typical supply current from VDD1 (IDD1) is less than 3 mA. When the part is in the recessive state, the supply current from VDD2 (IDD2) is typically less than 10 mA; in the dominant state, it is typically less than 75 mA; and when actively switching states at 1 Mbps, it is typically less than 55 mA with a default 60 Ω load installed. T 1 4 The bus voltage sense pin (VDD2SENSE), detects when VDD2 is connected on the bus side. A low on VDD2SENSE indicates that power is available on the bus side, and a high on VDD2SENSE indicates that power is absent from the bus side. CH1 2.00V CH3 2.00V VDD1 and VDD2 are the power supplies of the logic and bus sides, respectively. A 22 µF decoupling capacitor, C1, is fitted at the connector between VDD1 and GND1. Capacitors of 100 nF and 1 µF are fitted on the VDD1 and VDD2 pins, respectively, decoupling from GND1 and GND2. CH2 2.00V CH4 2.00V M1.00ms T 50.00% A CH1 1.80V Figure 2.
