CYCLONE V Starter Kit to AFE5809EVM

[Altera_Forum]

Hi, 

 I'm new to Altera devices, so excuse my simple question.  Can the Cyclone V Starter Kit connect to the AFE5809EVM via the HSMC connectors? To simplify, I wish to use the Cyclone V to read the LVDS serialised data from the AFE509EVM. Both PCB's have HSMC connectors so can they simply be connected with an appropriate HSMC cable? I only require ONE (1) channel from the AFE5809EVM, so its only two wires I am talking about here.  Thank you, Brett Neale

No, I'm afraid it doesn't look like it. The AFE5809EVM module has a narrower version of the Samtec connector as compared to Altera's HSMC. Also, the connectors are board-to-board (mezzanine) connectors and not intended to be connected via a cable. 

 You'll have to find another way of connecting the ADC to the FPGA.  Regards, Alex

Capture quantity and assemble into a packet data to send out via ethernet. Am I better off using a DSP for this purpose? There is no signal ananlysis required, so really just being able to read the ADC 14/12bit data, temporarily storing it, adding some framing data, adding a RTC time stamp, and spitting it out over ethernet. So I guess my question is: Would you use a FPGA or a DSP (or even a rasberry Pi) for this? My reason for the FPGA/DSP was reliability and flexibility. The main issue is reading the LVDS serialised data. Thank you in advance. Brett Adroit

A Raspberry Pi just won't handle the 640Mbps the AFE5809 has to offer. You'd end up operating it at such a low sample rate you'd be better off choosing something else. 

 If you don't need to process anything then an FPGA is certainly the way to go.  Cheers, Alex

I am new to FPGA's so any suggestions are more than welcome.  Bret

Hi Bret, 

 No, don't buy anything else - you certainly won't do any 'better' with a Cyclone IV kit. The kit you have is arguably better suited anyway. The GX parts have dedicated transceivers capable of very high speed i/o (>6Gbps). These would be ideal interfaces to use to the ADC (operating at a much lower speed).  Have a look through: transceiver architecture in cyclone v devices (http://www.altera.com/literature/hb/cyclone-v/cv_53001.pdf). Cyclone V GX parts will do a lot of the hard work for you.  Regards, Alex

So did it worked with HSMC-ADC-Bridge? If so i"ll be obliged if you let me know.  Thank You !!  Regards Nimish

It"ll be of great reference to me. Do let me know.  Best Regards, Nimish

Hi nimish,

I have the quartus project to deserialize the output of the AFE5809evm, this project is provided by texas instruments.

I opened another forum ( https://forums.intel.com/s/question/0D50P00004Hg59cSAB/afe5809evm-correct-use-of-evaluation-modules-and-the-cyclone-v-gx-starter-kit ),

It will be great if you can provide me any help, or any knowledge about this 2 devices, AFE5809evm and Cyclone V GX
