7. Quick Start – Board Configuration Check List
1. Start with EVB powered down/off.
2. Set the voltage supply DIP switches (Described in Section 2.2 Section 2.3) according to the following:
• Switch SW1 controls the voltage settings (either 1.5 V or 1.8 V) for the following supplies:
• VDD
• VDDA
• VDD_AUX
• Switch SW2 controls the voltage setting (either 1.0 V, 1.2 V, 1.5 V, or 1.8 V) for VDD_IO (voltage supply for output DIFF_0:7).
• Ensure that jumpers JP1:4 are installed.
3. Connect external clock input.
4. Determine the type of measurement.
• For phase noise measurements, no changes are required. Note that most phase noise analyzers have a single ended input, so
a balun should be added to convert the differential output to single ended.
• For signal integrity measurements, change resistors R37:R44 and R74:R81 from 0 to 953 ohms. They are all 402 size. Also,
add 2pF capacitors to C42:C49 and C65:C72. These are also all 402 size. After implementing this change, remember that if you
are observing the outputs via the SMA connectors to a 50 ohm input scope, the scale should be set to 1:20.
5. Configure the jumpers at JP5 and JP6 according to how you plan to test the part.
• Outputs 0:7 enabled/disabled
6. Set +5 V Select switch (SW3) based on how you will power the EVB, either via USB or via ex5 V supply.
7. Connect power, either via USB port or ex5 V power supply as chosen in previous step.
