AFE58JD48EVM: Query regarding the SPI mapping on FMC in schematic

Part Number: AFE58JD48EVM
Other Parts Discussed in Thread: AFE58JD48, LMK04826

Tool/software:

Hi there 

We are working with AFE58JD48 ADC mapping with FPGA card through FMC, we want to configure the DAC and ADC through FMC using SPI lines, but in the schematic there is no connection of SDOUT pin from ADC to FMC. In the schematic it is mapped on TSW_GPIO_10 but this signal is not connected on FMC. So can you look into this if there is some gap in my understanding.

 

Also the chip select of LMK04826 is not mapped on the FMC connector, so if we want to configure the LMK04826 through FPGA via FMC then how we can do this. 

So can you look into both the queries and an early response will be highly appreciated.

    Hi,

    Unfortunately TSW_GPIO_10 is not connected to FMC connector . You can use any other GPIO_PIN in the schematic like (TSW_GPIO_0/1/2/3) for the FMC connection and make sure to short them on sdout in the board. 

    Similar approach can be taken for chip select pin of lmk.
