Title: FMC connectors for ZedBoard
Post by: Hengist on August 28, 2014, 01:58:20 PM

Q: what FMC connector mates the ZedBoard one?

Trenz Electronic part number 23545 (http://shop.trenz-electronic.de/catalog/product_info.php?products_id=694) mates the FMC connector available on the ZedBoard.


The FPGA Mezzanine Card (FMC) standard (as defined in VITA 57) specifically targets FPGAs, increasing I/O flexibility and lowering costs in a broad range of applications (source: Xilinx white paper (http://www.xilinx.com/support/documentation/white_papers/wp315.pdf)).
To learn more about the FMC standard, ecosystem offerings, and roadmaps, see the VITA website (http://www.vita.com/fmc).
To learn more about FMC plans and products from Xilinx, see the Xilinx website (http://www.xilinx.com/fmc).
All male FMC connectors can mate with any of the female FMC connectors (source: Frequently Asked Questions About FMC (http://a.vita.com/home/MarketingAlliances/fmc/fmc_faq.pdf)).
Low Pin Count (LPC) connectors best mate Low Pin Count (LPC) connectors. High Pin Count (HPC) connectors best mate High Pin Count (HPC) connectors. Mating a HPC connector to a LPC connector, or vice versa, will function, however, some of the pins will be floating (= NC = "no-connects"). Source: Frequently Asked Questions About FMC (http://a.vita.com/home/MarketingAlliances/fmc/fmc_faq.pdf).
Several manufacturers supply FMC connectors; for instance, Samtec (http://www.samtec.com/standards/vita.aspx#vita57) and Molex (http://www.molex.com/product/searay.html) have suitable connectors.

ZedBoard features an "FMC (Low Pin Count)" connector (source: ZedBoard Technical Specifications (http://www.zedboard.org/content/zedboard-0)).
In its bill of matierial (http://www.zedboard.org/support/documentation/1521), part number Samtec ASP-134603-01 is listed. It is a female (receptacle) LPC FMC connector. This mates any male (plug) LPC FMC connector. We therefore recommend Trenz Electronic part number 23545 (http://shop.trenz-electronic.de/catalog/product_info.php?products_id=694) = Samtec ASP-134604-01.
