I’m getting ready to build some Parallella-RF modules and I’m a little curious about the clock design in the schematics.
Is there a particular reason for using an on-board clock, rather than the external clock that the Myriad-RF uses?
I’m also trying to build these relatively cheaply to play around with, so is there a huge downside to plating the boards with lead free solder instead of immersion gold? I’m also planning on using Isola 370HR instead of the IT-180A, since the IT-180A requires additional material adders and lead time from my PCB fab house.
Any input/ideas are appreciated! Thanks!
