GPIO vs HSMC pinout

Hi all, I am going to design high speed application. Because my cyclone V development kit (DE10- Standard) have two output options is GPIO and HSMC. I would like to know what the different betwe...

Hi,

1. HSMC:

  • It is a high speed connector, which supports 9.5GHz single ended signal and 10.5GHz for differential signal.Per pin current is around 2 A and good voltage rating.

    reliable in terms of the mating.

2. GPIO

  • Based on the frequency of fpga for high speed IO is around 500~600MHz only so we can use with in this frequency.

For high speed you can go with HSMC.

GPIO have LVDS pinout.
