Hello,
We want to implement our system with AFE5851EVM and TSW1400EVM.
And we try to follow the AFE5851EVM user guides.
But when we use the HSDC Pro to capture test data, it have "read DDR to File TIMED_OUT_ERROR Time Out error" error.
Some differences:
Hardware setup:
In the user guides, it has a bridge adapter between the AFE5851EVM and TSW1400EVM.
We have buy it, but haven't got it yet. So for now our hardware setup is like the second picture.
And the ADC power is 5VDC with 0.5 A.
Ext CLK IN is 40MHz and 13dBm(high 2.825V, low 0V)
My Questions : 1. Is bridge adapter necessary or it just to connect?
2. Does the hardware setup have any problem?
Software setup :
In the user guides, ADC5851 need to
init for TSW1400 -> Select TAB "TGC Register" -> press "Variable" toggle button -> enter 30 in the "Coarse Gain(dB)" field, then press "Write" button.
But the AFE5851EVM software in the TI web is like below picture. It does have "init for TSW1400", it just have"init for TSW1250".
So the Software setup is like
init for TSW1250 -> Select TAB "TGC Register" -> press "Variable" toggle button -> enter 30 in the "Coarse Gain(dB)" field, then press "Write" button.
My Questions :
1. Is the AFE5851 software version is right or not?
2. Is that we don't let the ADC to init for TSW1400 so that it have time out error?
p.s
In HSDC Pro setting, just choose AFE5851_12X firmware and set the ADC output data rate to 20MHz, and set the ADC input frequency to 2MHz.
