Hi guys, The caravel harness has a internal clock? . If it has, how could i use this clock? Should i feed some vccd to get it? Wich one? I need a 10 MHz clock to my device wich has a analog, RF and digital parts. If it hasnt it, i saw the harness has a external clock pin, but there is a "3.3 V clock" in the description. But my clock should be feed at 1.8 V.

As far as I can see you can either use the clk from the Wishbone bus (if you want to use the Wishbone bus) or you could use the user_clock2 (Independent clock - on independent integer divider), or you could use an analog pin (I would be afraid that the GPIOs might be too slow, but I am not sure). I guess other people will know more.
