Honored ContributorHow to use LVDS?
in datasheet,i find maybe it isn't similar to use LVDS in Cyclone1,cyclone2,and cyclone3, so what can i do if i want to use LVDS? 1,does it need resistor? 2,how many wire i need ? in my opin...

Honored ContributorHello stephenzhou. Yes, you should use external resistors in Altera and Xilinx.
I'm going to use LVDS too. And I have some questions. I have a devboard from Atmel with LVDS outputs and I want connect it with my Cyclone board. In datasheet I have read, that Atmel board has 100 Ohm termination resistors. So I can connect it directly to Cyclone pins. But distance between resistors and Cyclone device is very long( much longer, than recomend Altera). Will be it work? Can it damage chips?
