ADC3683EVM: What are now the best tools to evaluate this?

Part Number: ADC3683EVM
Other Parts Discussed in Thread: ADC3683, , TSW1418EVM, TSW14J50EVM, TSWDC155EVM

I want to evaluate the ADC3683, using the ADC3683EVM, which is readily available. What controller (such as the TSW1418EVM) and GUI (such as the SBAC271?) is recommended?

According to what I have seen, the TSW1400 is obsolete and no longer available, and the TSW1418EVM is also Obsolete, but still available in small numbers.

But if the TSW1418 is obsolete, then what is the recommended alternative?

    Hi Nigel,

    The TSW1418 is the capture card solution for this device.  It is no longer obsolete and can be purchased at the link below.

    Thank you... Can I confirm that the TSW14J50EVM is compatible? It appears to be, according to the TI website...

    Now I have spent time reading and re-reading the information about the two boards I realise this -

    1. The TSW14J50EVM uses an Intel/Altera Arria V FPGA that has been programmed to provide a JESD204 interface, but

    2. the TSW1418EVM has a totally different FPGA, a Xilinx Artix that has been programmed to use the serial LVDS interface used by the ADC3683.

    In theory of course the TSW14J50 could probably be reprogrammed to implement the serial LVDS interface, but it appears that it hasn't been developed to do that.

    Of course, any code developed for the Artix FPGA could not be used on the system based on the Arria V, as they are totally different devices, not even the same manufacturer...

    So I need to return the TSW14J50 that was ordered by a colleague in a bout of enthusiasm for the project, and ask for them to order a TSW1418 instead.

    If I am wrong, and it is possible to use the TSW14J50, if the system can be programmed to do that, then can someone please quickly say so.

    But I think that this is the answer to my problem - and the signposts out there still saying that the TSW1418EVM is Obsolete really are not helpful - e.g. Digikey (but Mouser does not have that message).

    I did also see on the TI website somewhere something that strongly suggested that the TSW14J50EVM was compatible with the ADC3683... I have a screengrab of it, but can't surrently find where I saw it.

    Hi Geoff

    Addendum:

    Discovering, now that I am trying it, that the TSW1418EVM is not a complete or ideal answer to evaluating the ADC3683EVM:

    https://e2e.ti.com/support/data-converters-group/data-converters/f/data-converters-forum/1348037/adc3683evm-what-practical-or-easy-to-implement-alternatives-are-there-to-using-the-default-external-clocks-on-j9-and-j7-on-this-evm

    The interface does not apparently drive the clocks needed to get the ADC3683EVM up and running (it seems that the FW doesn't exist?) - you need extra resources...

    Unless you know better?

    Thanks

    Nigel

    Hello,

    For future reference, the TSWDC155EVM will be used as the capture board for all devices in the ADC35xx/36xx family of parts. The TSW1418EVM and TSW1400EVM are no longer supported.

    Best,
