Cheers everyone! First of all, what a GREAT group this is. This is my first post here.
I've been building IQ transceiver, pretty much based on Gerald Youngblood's design. Now I have a small problem: I have reserved two AD9954 for the IQ vfo. My original plan was sync them BUT, I've heard that AD9954 can be used with even as high as 500MHz external reference clock. Is this true? In that case it is true, what can I expect from the max. output frequency? It just came to my mind, that I might also use just one AD9954 with 74ALVC74 or equivalent divider to form IQ vfo. My goal is to have 0-52MHz (160m to 6m) transceiver, so 52MHz*4 = 208 MHz is required from a single AD9954. Is this possible? 73 de Janne, OH1GTF PS.
