RFSDK: RFSDK error

Part Number: RFSDK
Other Parts Discussed in Thread: ADC12J4000, 66AK2L06

Hello 

I am using an ADC12J4000 EVM connected to the 66AK2L06 EVM via JESD204B interface directly.

There are no additional things connected to 66AK2L06 EVM.

I don't know that what error's reason

Traceback (most recent call last):

raise rfsdk.Error("Problem contacting the RFSDK service at %s:%d" % (self.address, self.port))
rfsdk.Error: Problem contacting the RFSDK service at 127.0.0.1:50001

Please tell me what can I do to fix the error?

  • Hello,

    There is a TI design, that has a User Guide, " www.ti.com/.../tidep0034 "

    You can request the latest RFSDK from the TI website. 2.07.

    You should obtain a DLC card,  The software for the DLC card is also needed, should be requested with RFSDK.  You will need to consult the ADC12J4000 EVM documentation, and download and install its GUI.  

    When you start the TI design, the GUI for the RFSDK needs to be targeted to the specific TI design.  The design guide " www.ti.com/.../tidu946a.pdf "  Figure 1, shows the connections of the module.

    If you do not have the DLC card.   You will need to configure the JESD ADC for an input clock, and it must output at the appropriate rate for the 2x60 245.76Msps (4.9152Gbps) complex or 2x75 368.64Msps (7.3728Gbps) complex over 2 JESD lanes.

    There is a JESD loopback that can be used with just the 66ak2l06 EVM , the JESD Tx is looped back to JESD Rx.   Note: there is a radio select, and use case file to configure the RFSDK, DFE, Serdes, and IQN for use.   If you do not have a DLC, then only the ADC board is plugged in, but the RFSDK software needs to be modified for the ADC-only use.  

    In the actual use case, the ADC has a direct down conversion from IF to baseband.   Then the DFE-Rx block and DFE-Rx-DDUC provide the 2 channels of Digital Down conversion.   

    Regards,

  • proposed_Det_Lat_Card.7zHello,

    I have attached the DLC card schematic, layout, and the GUI software.  You need to program the DLC card first, then the ADC12J4000 second, then the RFSDK sequences.

    Regards,
