ADC3683EVMCVAL: ADC3683EVMCVAL Interposer

Karl Gundal

Part Number: ADC3683EVMCVAL
Other Parts Discussed in Thread: ADC3683EVM, TSWDC155EVM

Tool/software:

The ADC3683EVM information indicates it comes with an Interposer board which was used to connect to the now obsolete TSW1400 via a Samtec QTH connector. Does the Interposer still come with the ADC3683EVM? If so is there a schematic for the Interposer board showing the translation of the FMC signals to the QTH connector? I am trying to connect the ADC3683EVM to a FPGA dev kit which has the mating QSH connector, configured for a Jetson MIPI CSI-2 arrangement, and the interposer might allow me to do that.

Hi Karl,

The ADC3683EVMCVAL version of the EVM has the FMC connector on it, so it would directly connect to the TSWDC155EVM (data capture board).

We are in the middle to moving over to a new data capture board, so thank you for your patience.

Any questions, please let us know.

Regards,

Rob

Hi, That did not answer the question. I know the current boards are designed with FMC in mind and the latest monitor board TSWDC155EVM has an FMC. The question was if the current ADC3683EVM still comes with the interposer and if there is a schematic for the Interposer. My current test setup needs the interposer. I am using an FPGA dev kit not the TSWDC155EVM. The FPGA Dev kit uses the QSH connector and I am trying to see if it is compatible.

Hi Karl,

See attached schematics.

Let me know if you want us to send you one.

Thank You for the fast replies. We reviewed the schematic and this interposer will not work for our test setup so no need to send a board.
