DAC328x Software Quick-Start Guide
1. Select the Top Level tab. This tab shows the most pertinent registers for the DAC, CDCE62005, and
TRF372017 devices. Press the Reset USB Port button.
2. The default configuration uses a 614.4-MHz DAC clock.
3. Set the RF output LO to the desired output frequency.
4. Toggle the Initialize button. This initializes the CDCE62005 clock and the TRF372017 synthesizer.
5. Verify that the CDCE62005 LED (D4) is illuminated, indicating lock.
6. Verify that the TRF372017 LED (D5) is illuminated, indicating the synthesizer is locked.
7. Monitor the output signal at the RF output connector. If default LO frequency of 2400 MHz is used and
3. Set the RF output LO to the desired output frequency.
4. Toggle the Initialize button. This initializes the CDCE62005 clock and the TRF372017 synthesizer.
5. Verify that the CDCE62005 LED (D4) is illuminated, indicating lock.
6. Verify that the TRF372017 LED (D5) is illuminated, indicating the synthesizer is locked.
7. Monitor the output signal at the RF output connector. If default LO frequency of 2400 MHz is used and
the TSW3100 is set up with two tones at 20 MHz and 21 MHz, then the tones seen in
are at
2420 MHz and 2421 MHz.
