5 Quick Start Procedure

1. Set VCCI/VCCO Power Supply to 3.3V and disable the power supply output
2. Connect positive terminal supply to TP5, and negative terminal to TP4
3. Ensure that cables connecting to IN+, IN-, IN+SENSE, IN-SENSE, OUT+, and OUT- are matched length and impedance. Perform any deskewing if necessary.
4. Set the function generator to produce a square wave output with 100mVpp at 50MHz, with a DC offset of 1.65V. Disable the signal generator output. Connect the output to IN+.
5. If available, use the second channel on the function generator to create a complementary signal to the one created in step 3. Disable the signal generator output. Connect the output to IN-.
6. If a second channel or another function generator is not available, use a power supply set to 1.65V. Disable the output and connect to IN-. An adapter to connect the SMA connector on the board may be needed.
7. Connect OUTP and OUTN to a 50Ω terminated scope. Alternatively, use a differential probe with a 100Ω termination and connect to the oscilloscope.
8. Connect IN+SENSE and IN-SENSE to a 50Ω terminated scope channel.
9. Enable the power supply and the signal generator.
10. Verify the supply current is < 17.5mA
11. Monitor and verify the inputs from IN+SENSE and IN-SENSE
12. Monitor and verify the outputs for OUT+ and OUT-

Next is a scopeshot capture of the inputs and outputs described in the quick start procedure. Here, the propagation delay between IN+ and OUTP/OUTN is measured by taking the time delta between when IN+ and IN- cross, and when OUT+ and OUT- cross. The low to high propagation delay in the figure below was calculated to be 682 ps.
