Not knowing exactly what that entails, in spite of the volume of useful
information you and others have dispensed on this list on that subject,
but always the hopeful engineer that I am :-), I wholeheartedly agree
Another approach I am interested in pursuing is the Thunderbolt
approach, where the 10 MHz is used (directly or via PLL or multiplier)
as the processor clock. That eliminates the sawtooth issue entirely, but
would limit the GPS engine to one that can be operated that way (with
the right clock frequency).
Either way, it sounds more fun than a serial converter.
However, it would be a fairly long term project for me, and for the
foreseeable future, I probably won't be able to dedicate enough time to
get such an ambitious project going.
Oh well, there is always retirement...
