DAC31x2EVM Configuration for DAC Output
Follow this procedure to configure the DAC31x2EVM in order to test the EVM signal output.
Step 1.
Four 0-
Ω resistors must be moved in order to configure the output of the DAC31x2 as 1:1
transformer-coupled.
Remove the resistors R109, R110, R111, and R112
Install the resistors R211, R207, R191, and R195
Step 2.
Provide the clock input: 491.52 MHz at 1.5 V
RMS at the J9 SMA connector of the
DAC31x2EVM.
Step 3.
Turn on power to the board at J12/J13.
Step 4.
Verify the spectrum using the Spectrum Analyzer at the two DAC outputs of the
DAC31x2EVM (J3 and J2).
Figure 5 illustrates a typical transformer-coupled output using a wave analyzer.
