1.3 Hardware Setup
Follow these steps (see Figure 1 ) to set up the hardware:
Step 1. Connect the TSW14J56 FMC interface connector (J4 of TSW14J56) to DAC38RF8x FMC
interface connector (J20 of DAC38RF8x EVM).
Step 2. Connect a USB 2.0 Type A to Mini-B cable from the PC to DAC38RF8x EVM USB Mini-B
port (J16).
Step 3. Connect a USB 3.0 Type A to Type B cable from the PC to TSW14J56 RevD USB 3.0 B port
(J9).
Step 4. Connect a 5-V power supply to the DAC38RF8x EVM board using J21.
Step 5. Connect a 5-V power supply to the TSW14J56 board using J11.
Step 6. Turn on the TSW14J56 board by moving switch 6 to the ON position.
Step 7. Connect the signal-generator output to LMKCLKIN (J4) of the DAC38RF8x EVM board.
• Configure the signal generator to output a frequency of 368.64 MHz with an amplitude of
10 dBm.
• Ensure that JP10 is removed from the board to enable internal clocking.
Step 8. Attach an oscilloscope probe to the alarm pin of DAC38RF8x EVM board (TP9).
