Hi All, Nick's request for a divide-by-three circuit to get his FE-405B to output a 10MHz signal got me thinking - didn't want to threadjack.
I had assumed that the FE-405B's DDS output and FE-5680 compatibility made it a good candidate for output frequency reprogramming. Has anyone determined that this is not possible? My biggest concern was that if the internal crystal is also at 10MHz you'd get bad spurs trying to output the DDS at the same frequency.. Does anyone know if the FE-405B uses the original FE-5680 DDS circuit or the more recent one that is only narrowly (EFC) tunable over the serial interface? Would be great to have a stable reference at 1, 5, 10, etc. MHz. Any info/references on the FE-XXX internals would be appreciated!
