Hari Krishna Posted July 29, 2019 Share Posted July 29, 2019 Hi, I need suggestions for interfacing 16 bit ADC with Atlys Spartan 6 FPGA Trainer board. Can i know what are the available interfaces with the board and any idea of how to do it. Link to comment Share on other sites More sharing options...
jpeyron Posted July 29, 2019 Share Posted July 29, 2019 Hi @Hari Krishna, Welcome to the Digilent Forums! We have a few ADC that would connect through the Pmod Port of the Atlys. The AD1 (2 channel 12 bit), AD2 (4 channel 12 bit) and AD5 (four channel 24 bit). The AD5 is the only one that meets the 16 bit metric. The Pmod AD5 communicates through SPI. Here are some projects done by Analog Discovery that might be helpful for your project. best regards, Jon Link to comment Share on other sites More sharing options...

jpeyron Posted July 29, 2019 Share Posted July 29, 2019 Hi @Hari Krishna, Digilent does not have a 2 channel 16 bit ADC that is above 100 Msps. I would suggest using a 3rd party VHDC ADC to meet your needs. best regards, Jon Link to comment Share on other sites More sharing options...
xc6lx45 Posted July 31, 2019 Share Posted July 31, 2019 search this forum for "ADC eval board". You'll find a lot of material to read. The problem is most likely more difficult than you'd like. Link to comment Share on other sites More sharing options...
zygot Posted August 4, 2019 Share Posted August 4, 2019 In a lot of ways the Atlys is still one of Digilent's better FPGA boards. The Spartan 6 on it has better IOSERDES performance than the newer Series 7 equipped Artix boards. Unfortunately, there are no add-on boards for it using the VHDC connector except for prototyping. Also unfortunate is that the differential IO to the VHDC connector has 50 series resistors complicating the usefulness of any differential IOSTANDARD options. The original Genesys is better in that regard but alas, not much in the way of add-on boards. You certainly could make your own ADC board but it wouldn't be a trivial undertaking. I do wish that I had a better answer to give you. Link to comment Share on other sites More sharing options...
