This section describes the setup and operation of the EVM for parameter performance evaluation. Figure 4-1 shows a typical test configuration of the ISOM8710 Opto-Emulator EVM using a signal generator, oscilliscope and a 5 V power supply .
ISOM8710DFFEVM has many "do not populate" (DNP) footprints for components which can be populated to apply different test conditions to the device. Section 4 lists and describes all the possible test configurations that can be acheived by modifying different components on the EVM.
| Component | Description |
|---|---|
| U1, C1, C2, R1 | To use ISOM8710 with a logic inverter, populate U1 with a standard logic inverter in a 5-pin SOT-23 package like the SN74LVC1G14DBV. Depopulate R1 and populate C1 and C2 with the appropriate decoupling capacitors as well. |
| R2, R3 | Current into ISOM8710 can be changed by replacing R2 with a different resistor value. The R3 footprint is also given to provide more resistor options. |
| R4 | Can be modified to provide some resistance to ground. |
| C3 | Can be added to test the device with additional input capacitance. |
| C5 | Can be populated to add additional decoupling capacitance. |
| R5 | If a pullup resistor is desired, populate R5. |
| R6, R7, C7 | One or more of these components can be added or modified to test the device with additional output impeadance, resistive or capacitive loads. |
