ADC12J4000EVM: ADC and LMK configuration

Ilya Denisov

Part Number: ADC12J4000EVM
Other Parts Discussed in Thread: ADC12J4000,

Hello!

We are supposed to work with a combo ADC12J4000 + Xilinx VC707 (Virtex 7 FPGA). We haven't received the ADC kit yet but, since our timetable for the project is quite pressing, we would be happy to have an example of how to configure the ADC and LMK registers so that we could use the kit in the following configurations:

1. 4Gsps raw ADC stream;

2. DDC with decimation factor 4 (1Gsps Re+Im).

Thank you in advance,

Kind regards,

Ilya.

Ilya,

If you were to use the ADC12J4000EVM with the TI TSW14J10EVM, you could use the HSDC Pro GUI to capture data. You would just need to follow the example shown in the attachment. If you plan on plugging the ADC directly into the VC707 and using your own firmware, the log file attached is what we use to configure the ADC12J4000EVM with.

Regards,

Jim

Jim,

I'm working with ADC12J4000EVM too. It seems that Ilya's question #1 is my case (I need full BW=2gsps, Fs=4gsps). I cannot figure out how to configure the ADC for that case. Is it possible to show the register settings for LKM and ADC itself for my case.

Thanks is advance.

-D.

If you are using this board with a VC707 and the TI example firmware, the config files are attached for the ADC EVM.

Jim,

could you please point to the ref design you are reffering to?

is it slac690.zip archive?

-thanks in advance

P.S.

I just found the files you mentioned about. Apparently TI firmware is included with HSDC Pro Software.

one more question. Is it possible to work with adc12j4000evm directly in conjunction with vc707 dev kit without the TSW14J10 evm?

-Thanks

Dmitri,

The ADC12J4000EVM can be plugged directly into the VC707 but you would have to provide the FPGA firmware. HSDC Pro will not work with this setup.

Jim
