[hpsdr] Odyssey Siren Design

[Giancarlo Moda]

Hi All,

regarding this design due to the low frequency IF I
would suggest to use for the Digital Quadrature
Generator one 74ACT74 and in place of the two 2G53 use
the FST3125.
With this set up you will power these two ICs at +5V
as for the OPAs.
The FST3125 gates will be driven directly with all
four phases by the 74ACT74 DQG.

I believe you can see the potential benefits here also
are easy to purchase components.
