Hi Kelvin, Just a trivial point.
The Si570 is not actually a DDS device, uses a completely different method of generating the final frequency. The net result is that the Si570 has a much clearer output spectrum, and none of the spurs usually associated with DDS chips, also the Si570 has lower phase noise. Although it does cost a little more, certainly worth it. It has has become the 'standard' oscillator source now for a number of different SDR projects. 73, Bob G8VOI --- In [email protected], "kcmuthumani" <kelv...@...> wrote: > > Hi Pete. > > This SDR looks very nice, before I order one do you have some specs on the > unit ?
