AFE7950EVM: TSW14J58

Part Number: AFE7950EVM
Other Parts Discussed in Thread: TSW14J58EVM

Tool/software:

Hi,

The two devices are TSW14J58EVM and AFE7950EVM.

The current relevant settings are shown in the figure.
SysParams. FRef = 491.52
SysParams. FadcRx = 2949.12
SysParams. FadcFb = 2949.12
SysParams. Fdac = 2949.12 * 4
sysParams. DdcFactorRx = [12,12,12,12]
sysParams. DucFactorTx = [24,24,24,24]
The actual DAC sampling rate is 2949.12*4/24, and the ADC sampling rate is 2949.12/12, both of which do not reach the GHz level. What is the maximum sampling rate of this device? I hope to adjust the relevant parameter settings to maximize the actual sampling rate of both DAC and ADC.
In addition, I want to use the device to collect four channels of data at the same time, what command statement should I use?

Thank you very much!

All the best!

    Hi,

     

    Thank you for choosing TI High Speed Converter products. I am sorry to inform that our applications team for high speed data converters does not have the bandwidth available to support University inquiries at this time. If resource bandwidth becomes available, we will follow up with this question.

     

     

    Regards,

    Hi,

    Thanks for your reply!

    I want to use multiple Rx channels to collect data at the same time, is this possible? If possible, I hope you can give the corresponding command statement, I really need this function, thanks again!

    All the best!
