EVALUATION KIT CONTENTS EVAL-ADM3051EBZ GENERAL DESCRIPTION The EVAL-ADM3051EBZ allows quick and easy evaluation of the ADM3051 CAN transceiver. 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 ADM3051, is a controller area network (CAN) physical layer transceiver, allowing a protocol layer CAN controller to access the physical layer bus. The ADM3051 complies with the ISO 11898 standard. It is capable of running at data rates of up to 1 Mbps. For evaluation with a bus cable, a screw terminal block is provided to allow connection of CANH and CANL signals and connection of the cable shield. PLEASE SEE THE LAST PAGE FOR AN IMPORTANT WARNING AND LEGAL TERMS AND CONDITIONS. The operating mode of the ADM3051 can be selected by jumper configuration. Three operating modes are available: high speed, slope control, and standby. Selecting standby mode connects Pin 8 (RS) of the ADM3051 to VCC, placing the device in a low current standby mode. Selecting slope control mode limits EMI by connecting RS with a 47 kΩ resistor to ground to modify the rise and fall of slopes. This mode facilitates the use of unshielded cables. Alternatively, selecting high speed mode disables slope control by connecting RS to ground, allowing high speed operation. Shielded cables or other measures to control EMI are necessary in this mode.

The evaluation board allows all of the input and output functions to be exercised without the need for external components. An example operation of the EVAL-ADM3051EBZ is shown in Figure 2. Ensure that LK3 is in Position B (high speed mode). Connect a clock generator on TxD and set up a 500 kHz square wave clock with output swing between 0 V and 5 V. Connect the scope probes to the CANH and CANL test points. A plot of the oscilloscope for TxD, RxD, CANH, and CANL is shown in Figure 3. Channel 1 shows the TxD signal, Channel 4 shows the RxD signal, and Channel 2 and Channel 3 show the CANH and CANL signals, respectively. On the EVAL-ADM3051EBZ, the power is connected to VCC. A 22 µF decoupling capacitor, C1, is fitted between VCC and GND at the J1 board connector, and a 100 nF capacitor (C2 in Figure 4) is fitted at the ADM3051 device. With the default 60 Ω load installed, the typical supply current (ICC) is as follows: • • • Recessive state: 5 mA Clock at 1 Mbps: 40 mA Clock at 250 kbps (slope control mode): 34 mA In standby, with the bus in a recessive state, typical ICC is
