The bus pins are robust to ESD events, with high levels of protection to Human-Body Model and IEC Contact Discharge specifications. These devices each combine a differential driver and a differential receiver, which operate from a single 3.3-V power supply.The driver differential outputs and the receiver differential inputs are connected internally to form a bus port suitable for half-duplex (two-wire bus) communication. These devices all feature a wide common-mode voltage range making the devices suitable for multi-point applications over long cable runs. These devices are characterized from -40°C to 125°C. NOTE: The EVM board comes with the SN65HVD75 (20 Mbps) device soldered on the board. The EVM kit comes with an IC sample pack that includes one SN65HVD72 (250 kbps) device and one SN65HVD78 (50 Mbps) device. Either device can be evaluated by replacing the SN65HVD75 with the desired speed grade device. 2 EVM Setup and Precautions Figure 1 shows the schematic of the EVM. The EVM board has headers labeled from JMP1 to JMP14 (JMP5 is omitted) and two 3-pin terminal blocks labeled TB1 and TB2. These headers support device evaluation for a wide range of system configurations. • Pin 1 (EARTH) is a second ground pin that allows applying an external voltage between GND and EARTH to simulate common-mode voltage conditions. • Pin 2 (GND) is connected to the negative output or ground terminal of the PSU. This pin represents the ground potential of the device-under-test and the entire EVM. It also connects to various jumpers on the board. • Pin 3 (VCC) is connected to the positive output of a regulated 3.3-V power supply unit (PSU) as it represents the positive supply voltage of the device-under-test and also connects to various jumpers on the board. 2 SN65HVD7xEVM Evaluation Module SLLU162 – March 2012 Submit Documentation Feedback Copyright © 2012, Texas Instruments Incorporated EVM Setup and Precautions www.ti.com 3PIN_TERMINAL_BLOCK TB1 DUT_VCC DUT_VCC 1 DUT_VCC 2 DUT_GND JMP8 1 2 EARTH_GND 3 4 VCM_A JMP10 C8 DUT_GND 1 UNINSTALLED 2 Header 4x1 3 DUT_GND EARTH_GND 4 DUT_VCC VCM_B VCM_B JMP9 Header 4x1 1 EARTH_GND 2 3 4 C9 DUT_GND UNINSTALLED VCM_B Header 4x1 DUT_GND EARTH_GND 3 D1 1 R1 2 VCM_A 1k Ohms BLUE LED Diode DUT_GND C1 1uF C2 0.1uF EARTH_GND C4 1uF C5 0.1uF R10 0 Ohm DUT_GND JMP11 3 2 1 R_1 DUT_GND R RED LED Diode D3 DUT_GND Header 3x1 Header 4x1 R6 UNINSTALLED 2 1 2 3 4 C6 UNINSTALLED EARTH_GND EARTH_GND DUT_GND DUT_VCC JMP2 R11 1k Ohms /RE 1 2 3 4 3 2 1 DUT_GND Header 4x1 DUT_GND EARTH_GND R2 50 Ohms VCC B A GND EARTH_GND 3PIN_TERMINAL_BLOCK JMP6 JMP7 R5 120 Ohm 1 2 3 4 C7 UNINSTALLED 1 2 3 4 D2 GREEN LED Diode R3 50 Ohms 2 3 Header 4x1 Header 4x1 TB2 EARTH_GND EARTH_GND R9 A 2 DUT_GND 1 DUT_GND 1 EARTH_GND 3 2 1 DUT_GND R /RE DE D EARTH_GND 8 7 6 5 EARTH_GND JMP13 DE C3 R14 1k Ohms EARTH_GND DUT_VCC 1 2 3 4 B_2 0 Ohm SN65HVD7x Header 3x1 JMP3 R8 B 0.01uF U1 JMP12 1 2 3 4 DUT_VCC DUT_GND 1 DUT_VCC JMP1 A_2 R7 UNINSTALLED 0 Ohm DUT_GND Header 3x1 Header 4x1 EARTH_GND VCM_A EARTH_GND EARTH_GND DUT_VCC JMP4 NOTE: R2, R3, R4 - DNI JMP14 1 2 3 4 D 3 2 1 DUT_GND Header 4x1 DUT_GND R4 50 Ohms Header 3x1 EARTH_GND EARTH_GND EARTH_GND Figure 1.

Bridging DUT_GND with EARTH_GND While JMP2 to JMP4 are stimulation points, or headers through which the control and data signals for the SN65HVD7x are applied, JMP1, and JMP11 to JMP14 are probe points, or headers at which these signal can be measured. Note that the 50-Ω resistors, R2, R3, and R4, have the index n.a., indicating that these components are not assembled. Because signal generators have a typical source impedance of 50 Ω, their output signal is twice the required signal voltage, and assumes that the on-board 50-Ω resistors divide this voltage down to the correct signal level. SLLU162 – March 2012 Submit Documentation Feedback SN65HVD7xEVM Evaluation Module Copyright © 2012, Texas Instruments Incorporated 3 Powering Up the EVM and Taking Measurements www.ti.com Without these resistors; however, this voltage divider action is not accomplished, and the generator output voltage must be reduced to 3.3 V to avoid damaging the transceiver inputs. Signal Generator Scope 3.3V Ch1 Ch2 JMP4 1 2 3 4 VCC JMP14 1 2 3 D - input of SN65HVD7x Figure 3. Example for Stimulus and Probe Points with JMP4 and JMP14 Figure 3 gives an example for entering a data signal into the driver section of the transceiver. The signal output of the generator is adjusted to 3.3 V. The generator’s ground terminal is connected with pin 3, and the signal output terminal with pin 2 of JMP4. The data signal is measured through an oscilloscope with its signal input connected to pin 1 and its ground wire connected to pin 2 of JMP14. The same setup applies to the DE and RE inputs through their corresponding headers JMP2 and JMP12 and JMP3 and JMP13. JMP1 however, must not receive a signal stimulus. Like JMP11, it represents the receiver output, R, of the SN65HVD7x. Instead of using signal generators, the EVM can directly interface to the micro controller I/O. Then the non-assembled 50-Ω resistors are of no concern. However, for proper operation, it must be assured that the high-level input voltage VIH ≥ 2 V and the low-level input voltage VIL ≤ 0.8 V. 3 Powering Up the EVM and Taking Measurements The generally recommended procedure for taking measurements is listed: 1. Install the required ground connections. 2. Connect the oscilloscope with the respective probe points you want to measure. 3. Adjust the power-supply to 3.3 V. 4. Adjust the generator outputs for a 3.3-V maximum output signal level, or check the logic switching levels of the controller I/O. 5. Connect the power supply conductor with pin 3 of TB1 and observe the blue LED (D1) turning on. 6. Connect signal conductors from the controller or the generator with their corresponding EVM inputs at JMP2 to JMP4. 7. Logic high at the receiver output, R, will turn on the red LED (D3), and logic high at the driver input, D, turns on the green LED (D2). If D is left open, an internal 100-kΩ pull-up resistor provides logic high instead. However, due to the small input current, D2 will remain off. 3.1 Measurement Examples Each of the following measurement examples show the equivalent circuit diagram and the corresponding EVM setup. Only the measurement relevant headers and terminal blocks are shown, and not necessarily at their exact location on the EVM. 1. Standard Transceiver Configuration Normal transceiver operation requires both the driver and the receiver sections being active. Therefore, the receiver enable pin (RE) must be at logic low potential and the driver enable pin (DE) at logic high. Transmit data entering at the D-input terminal appear as the differential output voltage (VOD = VA – VB) on the bus wires, A and B. Via the active receiver, it is possible to sense the data traffic in transmit direction. 4 SN65HVD7xEVM Evaluation Module SLLU162 – March 2012 Submit Documentation Feedback Copyright © 2012, Texas Instruments Incorporated Powering Up the EVM and Taking Measurements www.ti.com DUT_VCC U1 Receive Data 0V 3.3V Transmit Data R 1 RE 2 7 B DE 3 6 A D 4 5 GND Vcc 8 R8 B B 0W R5 120 W VOD R9 A VB 0W A VA Figure 4.

EARTH and GND receive the same reference potential, PSU-ground, through the wire-bridge from pin 1 to pin 2 at the terminal block, TB1, while pin 3 (VCC) is connected to the 3.3-V output of a power-supply unit (PSU).

SN65HVD7xEVM Setup for Normal Transceiver Operation The low potential for RE is provided by the wire-bridge from pin 2 to pin 3 at JMP2, and the high potential for DE through a wire-bridge from pin 2 to pin 1 at JMP3. Data from the signal generator enter the board at pin 2 and pin 3 of JMP4. This data is measured via channel 1, which is connected to pin 1 and pin 2 of JMP14. Channel 2 measures the receive data at JMP11, and channels 3 and 4 the bus voltages, VA and VB, at JMP6. 2. Operation Under Maximum Load EIA-485 (RS-485) specifies three maximum load parameters: a maximum differential load of 60 Ω, a maximum common-mode load of 375 Ω for each bus wire, and a receiver common-mode voltage range from –7 V to +12 V. Figure 6 reflects these requirements through R5, R8, R9, and VCM. Note that under maximum load conditions the transceiver must be capable of sourcing and sinking bus currents of up to 55 mA. The purpose of this test is to show the robustness of VOD over the entire commonmode voltage range at maximum load.

Configuration for Maximum Loading While the cable connections of the signal generator and the oscilloscope remain the same as in the previous example, the following board changes need to be implemented to reflect maximum load conditions: • replace R5 (120-Ω default) with 60 Ω • replace R8 and R9 (0-Ω default) with 375 Ω • connect pin 2 of JMP7 with pin 1 and pin 3 with pin 4 • replace the previous wire-bridge at TB1 with a second power supply unit (PSU2) and connect the ground terminals of both, PSU1 and PSU2 with a wire-bridge, as shown in Figure 7.
