Part Number: AFE7950EVM
Other Parts Discussed in Thread: LMK04828
I want to use the external clock mode on the AFE7950EVM.
Fref 11520MHz, FadcRx 2880MHz, FDac 11520MHz
I changed the AFE7950EVM hardware and Latte
1> hardware
Remove R372, R373, R368, R369
Insert R370, R371, R366, R367, L40, L41
Insert C80, C81
2> Latte
setupParams.skipFpga = 1
sysParams = AFE.systemParams
setupParams.fpgaRefClk = 180
AFE.systemStatus.loadTrims = 1
sysParams.externalClockTx = True
sysParams.externalClockRx = True
sysParams.FRef = 11520
sysParams.FadcRx = 2880
sysParams.FadcFb = 2880
sysParams.Fdac = 11520
## The following parameters sets up the LMK04828 clocking schemes
lmkParams.pllEn = True
lmkParams.inputClk = 2880
lmkParams.sysrefFreq = 0.06
lmkParams.lmkFrefClk = False
Message printed by Latte after run
Couldn't get the link up for device RX: 1; Alarms: 0xbfc0
