AD-FMCOMMS1-EBZ FRU

Hi,

I have designed a custom board based on AD-FMCOMMS1-EBZ.
The modification i did was instead of using two ADF4351s, i'm using one ADF5355 to supply LO for both Modulator and Demodulator.

I have below questions

1. Can the board power up correctly without FRU?
2. Where does the FRU information stored in the AD-FMCOMMS1-EBZ ?

Thanks !

Regards,
Anojh

    Hi Anojh,

    You can find more info about FRU here: https://wiki.analog.com/resources/eval/user-guides/ad-fmcomms1-ebz/software/linux/applications/fru_dump

    "1. Can the board power up correctly without FRU?" -- as far as I know it depends on the carrier. There are carriers which checking the FRU image, mainly to check the VADJ level, there are others that don't.

    Let us know if you still have questions.

    Thanks,

  • Hi Istvan,

    Thanks for your reply.

    So far all the supplies are correct. but i encounter a problem with the AD9122. it doesn't show up in the iio:devices 

    I get below kernel messages at boot-up

    cf_axi_dds 74204000.cf-ad9122-core-lpc: DRP unlocked.
    cf_axi_dds: probe of 74204000.cf-ad9122-core-lpc failed with error -110

    I'm attaching the entire log for your reference.

  • Hi Istvan,

    When i remove the output termination resistors (100 Ohm) of AD9523 clocks, the DAC started working. The ref schematic doesn't have these resistors. But i have added them in my design and mistakenly inserted them.   

    Can you verify that below devices are correct and i'm not missing any further devices ?
