4 EVM Setup and Operation

Basic EVM Setup

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 .

Figure 4-1 Basic EVM Operation

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.

Table 4-1 Component Configurations
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.
