TSW14J56EVM: Read raw data from FMC

Part Number: TSW14J56EVM

Dear all,
Hi.
I hope that everyone is doing well.
I have a question about the TSW14J56EVM paired with ADC34J45EVM.


If I want to make a process on the raw data or filter them for example, is it possible to read the raw data in 14bit from the FMC before encoding them?


Since (according to the instruction) the board is designed to receive the serial by the JSEB204B protocol, I wonder if it’s possible to access the raw 14bit data from the FMC for each channel.

Thanks.
Fernando.

    Hi Fernando,

    If I understand your question correctly, you want to access the raw ADC data before it is transmitted over the JESD protocol? If this is the case, then this is not possible. Data is not transmitted until the JESD link has been established between the ADC and FPGA.

    The LVDS version of this part (ADC3444) has a slower sampling rate (125 MSPS), but has data at the outputs available while the ADC is sampling.

    Best Regards,

    Dan
