LVDS signal to Desktop computer/Laptop computer

Other Parts Discussed in Thread: TUSB1310A

Hi,

 

I have an 8 channel high throughput ADC running at 65Msps and 14 bits conversion. So the digital data rate i am having is 113MBps per channel (correct me if i am wrong).
What would be the best approach to interface this raw data in LVDS to my computer, without using PCI card? Is USB 3.0 my only choice? And what exactly is the reason i need to use FIFO?

 

 

Thank you

Michael

    Michael,

    You will need to convert it to some prootocol or use an off-the-shelf data acquistion board (which you said you do not want to do) to get it into your PC. 

    USB 3.0 would be an option, but that would also most likely require buying a PCIe add-in acard as very few PC ship today with USB 3.0 native.  However, to get that data into USB 3.0 format would require an external FPGA with a  USB 3.0 digital core and our TUSB1310A.  There is presently no general purpose USB 3.0 peripheral device available.

    Buying some sort of data acquistion board would most likely be the lowest cost and fastest method for you to use.

    DHarmon,

     

    Thank you for your reply.I forgot to mention that, this high speed data acquisition project is my Senior Design Capstone project, so buying "off the shelf" product is obviously not an option for us.

     

    regards,

    Since off the shelf is not an option, going the USB 3.0 route or possibly a 1394 Firewire route could be an option, but in either case there is not a single chip solution that will do this.
