Hi Dan, I have the Sync lines for each DAC connected to the FPGA - the second connection was made to LA_33_P/N_A (pin G36/37 on the FMC) so that either IC can request a sync. I'll be modifying the TSW...

Rita, After you loaded the DAC registers and applied a reference clock, did you tune the PLL VCO? This is required to get the VCO to lock to the reference frequency. Regards, Jim

Jim hi. Thanks. Now I don't understand the clocking scheme of the EVM. Why LMX2581 is not programmed? I don't have a chance to use GUI. The evm board I have is controlled only through SPI routed to FMC...

Hi MT, Thanks for sharing that. It seems clear that the GUI is stuck since it is not receiving an acknowledgement from the microcontroller on the EVM. Are you simply monitoring the SPI bus, or are you...

Thanks, Dan. Are the grounds shared between the EVM and your signal generator? A 200-mV input signal should not cause the ADC output to clip like this, especially since all channels are set to Gain = 1...
