Honored ContributorHi Dave,
I have decided to come back to this post, in order to give some updates and maybe share some knowledge for whoever would like to interface the ADC12D1800RFRB to his/her Altera FPGA board. We have actually found an HSMC to FMC adapter developed by Kayan Instruments. The point is that it doesn´t really do the job while is just rounting pins for the LPC standard. It allows us to read just two channels out of the ADC. As you mentione in your answer some time ago, our ADC is deserializing the data into 4 channels of 900 MHz each. Each channel is bringing samples of our RF signal interleaved (namely for the instants t, t+1, t+2, t+3). We could do some routing efforts on the Virtex 4 FGPA, coming with the ADC12D1800RF Reference Board, but the point is that we would like to be able to manage such datarates on our Altera development board. The option of using an Arria V Development kit would be to take into account as you mentioned some time ago, but reading the manual it seems like it is conceived in order to be used with QAM DACs. Also on the TI page we see examples of configuration using ArriaV and the DAC34SH84 EVM, connected to the FMC connector through an apposite adapter. My colleague also pointed out that for our application, where we would like to read the whole 4 ADC channels, the connector on the ArriaV is still missing the mapping of some signals which we would need. Looking around on the internet, we still couldn´t find examples of people interfacing such ADC board to an Altera device. I case of any news I will come back to this post. Cheers, Giovanni
