Spartan 6 Starter kit SP605 FGG484LX45T - LVDS interface pins out

Jump to solution

Hello,

 

I am very new to FPGA. I have some basic question about FPGA connections. 

 

I am trying to read data output from a Time-to-digital converter chip (TDC-GPX2) via LVDS interface. I already bought Spartan 6 starter kit SP605. I plan to connect output pins (LVDS signals) from the TDC chip to the FPGA via FMC card (ug537). I thought FMC will allow me to access all pins on this FPGA.

 

From what I read in Spartan 6 I/O Resources, LVDS input can be used from any banks and LVDS outputs only from bank 0 and bank 2.  When I look at pins on bank 0 and 2 in document Spartan 6 Packaging and Pinouts ( ug385), I did not see any pins matched with any pins on FMC connector. I am very confused right now. How do I know which pins on FMC card belong to which banks so I can connect accordingly. Any help/hints will be great. Thank you.

@lnguyen1  The mapping from FPGA to FMC is done by the board documentation. See page 54 here

UG385 refers to the FPGA chip alone.
