DS91M047 Evaluation in a Point-to-Point Link
The following is a recommended procedure for using and evaluating the DS91M047EVK. Figure 2 depicts a
typical setup and instrumentation used.
1. Select a single DS91M047 evaluation board.
2. Apply the power to the board (3.3 V typical) between J1 and J2 power tabs, observe the value of I
CC,
and compare it with the expected value (refer to the datasheet) to ensure that the devices are
functional.
3. Enable U1 driver outputs. This is accomplished by setting the EN pin to VDD (JP1) or EN* pin to GND
(JP2).
4. Connect a signal source to one of the driver inputs (DI0-3).
5. Connect one of the U1 outputs (A0-3/B0-3) to an oscilloscope and observe the waveforms.
