Just a quick photo-op of the completed SI5351 bolted onto a SA612 mixer. 

This 5351 design uses a big external crystal because I don't have the tiny SMD ones, but when I do another component order I'll get some of the ones used in the Etherkit 5351 breakout and send the board to a PCB fab. For now this is fine for a test to see if the design makes sense.
