> Noise like the oncore sawtooth isn't always a bad thing. I was going to comment on that area... Thanks for the reminder.
The problem is that the sawtooth isn't noise in the normal Gaussian sense. If you happen to hit a long/wide hanging bridge, the resulting offset may get past your PLL filter. It might be possible to avoid hanging bridges by dithering the sawtooth. I'm thinking of something like a heater under the xtal for the GPS unit that gets driven by a medium frequency - slow relative to the normal sawtooth but fast relative to the PLL time constant. This somehow feels not-good, but I can't see the obvious screwup. -- These are my opinions, not necessarily my employer's.
