Hi,
I need a variable RF signal output of 130 MHz to 210 MHz, so I am testing AD9144.
I happen to have FMCDAQ2-EBZ & ZCU102 board, So for a simple experiment, the environment was constructed as attached to the link below
https://wiki.analog.com/resources/eval/user-guides/ad-fmcdaq2-ebz/quickstart/zcu102
In addition, it produced a signal output of 200 MHz, and as shown in the figure above, an incomplete sine wave was output due to insufficient sampling.
When I checked the setting, the sampling frequency was set to 1GHz, so I tried to change to 2.8G sampling rate, which is the maximum frequency of AD9144, but it didn't work out.
Then I found the wiki as below,
https://wiki.analog.com/resources/eval/user-guides/ad-fmcdaq2-ebz/clocking ( AD-FMCDAQ2-EBZ Clocking )
According to Wiki, the FMCDAQ2 system uses the AD9523-1 PLL2 (3GHz) divided by a value between 3 and 5, so the maximum master frequency is 1 GHz, and the DAC is described as having a maximum frequency of 1 GHz.
Can't I have DAC with 2.8 GHz Sampling in this system?
