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 between them? Could I use GPIO pinout for high speed application? Is GPIO LVDS pinout?
--- Quote Start --- Hi John, With Single Ended GPIO (not LVDS) don't go over 100 MHz with DE10 to avoid troubles. --- Quote End --- What do you mean about "Single Ended GPIO"? On the DE10 user manual, it's just mentioned about GPIO. It doesn't say any thing else.
You have GPIO header with 2.54mm pin strip.When you use a pin as a single pin you usually call it Single-Ended https://en.wikipedia.org/wiki/single-ended_signaling You can use a couple of (special) pins in GPIO header of DE10 as LVDS https://en.wikipedia.org/wiki/low-voltage_differential_signaling
