Tool/software:
Hi,
I am trying to configure the AFE7950 EVM board with AFE79XX Lattice GUI.
For FadcRx, Fref and Fdac, if I am giving the values as shown below and run the buffer I am not getting any error :
sysParams.fbEnable = [False]*2
sysParams.externalClockTx = False
sysParams.externalClockRx = False
sysParams.FRef = 491.52
sysParams.FadcRx = 2949.12
sysParams.FadcFb = 2949.12
sysParams.Fdac = 2949.12*4
decimation = 6
interpolation = 24
With the above configuration its running fine.
But, I need Fadc as 1.966.08Mhz. So I have made the changes as shown below:
sysParams.FRef = 491.52
sysParams.FadcRx = 1966.08
sysParams.FadcFb = 1966.08
sysParams.Fdac = 1966.08*4
sysParams.externalClockRx=False
sysParams.externalClockTx=False
decimation = 4
interpolation = 16
Also I have changed the Top System Parameters in the AFE79xx_SystemParameters excel sheet at the location: C:\Users\..\Texas Instruments\AFE79xxLatte\lib\Afe79xxLibraries\AFE79xxLibraryPG1p0\resourceFiles.
But there I am getting error as shown in the below snapshot.
Could you please provide the details of what all configuration parameters and files that we need to change if we are changing fadc and fdac ?
