HSMC Specification

[Altera_Forum]

Hello, 

 the Cyclone III FPGA Starter Board Reference Manual says:  "For more information regarding the HSMC, refer to the High Speed Mezzanine Card Electrical and Mechanical Specification version 1.2 or later."  Where can i get this specification? I can't find it one the Altera website.  Thanks in advance! Michael

--- Quote Start ---  You can use the differential pairs as 2 single ended I/Os. You can of course use only one pin of the pair and leave the other unconnected.  --- Quote End ---    How to use differential pairs as 2 single ended IO? What configuration to set in Quartus or hardware? As far as I know, I thought to use single ended IO, I just need to reconfigure it at pin planner so that it has IO standard 2.5V instead of LVDS isnt it? Please correct me if I am wrong because I am currently configuring the HSMC pins.  thank you.

You would really help me out with those HSMC eagle footprints. If anyone has them, please send them to me! 

Thank you very much!

(If somebody is interested in an EAGLE footprint for this connector, let me know.)  --- Quote End ---    Hi all, if anyone still watches this thread, could you please send me the HSMC Eagle footprints? My email is fc39df4c@opayq.com Thank you very much!
