JESD204B tx_sync/rx_sync

Jump to solution

Hi,

I'm trying to connect the JESD204B IP as shown below.  There is not much documentation on the tx_sync and rx_sync signals.  So, I am wondering if they should just be connected together?

Thanks,
Dan

Hi @edadangtri 

You just find the sync ports at Analog Devices AD9371.

Conncet JESD RX SYNC output to AD9371 TX SYNC input.

Conncet AD9371 RX SYNC output to JESD TX SYNC input.

Hi @edadangtri 

JESD204 designed to connect Analog-to-Digital Converter (ADCs) and Digital-to-Analog Converter (DACs) to logic devices.

Analog-to-Digital Converter(Tx) to FPGA JESD (RX).

FPGA JESD (TX) to Digital-to-Analog Converter(RX).

Sync signal is output of RX and is connected to TX input.

Are you looking to interafce FPGA JESD (TX) to FPGA JESD (RX) then you can conncet Sync signal.

Hi,

I am attaching a more detailed block diagram of my implementation.  As you can see, I am using the JESD204B IP to talk to an Analog Devices AD9371 transceiver.  I expect to send data by writing (via AXI) to the JESD204B tx core and I will receive data by reading from the rx core.  So, for this case...should I connect rx_sync and tx_sync together?

Thanks,
Dan
