You can call the ad9122_set_interpol() function (https://github.com/analogdevicesinc/no-OS/blob/master/fmcomms1/AD9122/AD9122.c#L588) or you can change the interpolation factor from the ad9122_setup() function (https://github.com/analogdevicesinc…
I use ADF4350 generate 2600MHZ LO single_end to ADL5375 , the input of I and Q for AD9122 is a constant, then generate 1MHZ NCO low sideband to modulate a the constant , that is , the output of AD9122 is 1MHZ single frequency ,
You can use AD9122 + ADL5375 to get 400MHz to 4G output with 70MHz bandwidth. AD9122 output center frequency depends on the configuration of NCO and HB filters. you can find the details in the datasheet. As for the output between 10MHz and 400MHz…
It looks like you are feeding Data to AD9122 at 435MSPS, is this frequency fixed or does it change? The AD9122 has Phase and amplitude adjustment you needed.
What output frequency IF are you trying to come out of the AD9122 with. Are you using the interpolation…
I have been trying to interface DAC AD9122-M5372-EBZ with Zynq ZC702. I find quick guide
and reference designed for ML605 with AD9122
Try this link for an example of how to use the AD9122 eval board with something other than the DPG2.
Assuming that you are asking AD9122, right?
1. left floating.
2. Yes. Refer AD9122 EVB schematic.
we design the transceiver with ad9122, how to get ad9122 reference design?
What is the Maximum input data rate the AD9122 can handle and what is the maximum bandwidth the AD9122 can support?
