That's fine. Just set the oscillator to keep the bridge in the
middle of the range. It should be possible to detect the correct
frequency and phase by monitoring the sawtooth correction data from
Now you have eliminated the sawtooth error and no longer have to add
correction for it.
This will eliminate the quantization error in the sawtooth
correction data since it is no longer needed. If the 1pps loop is
properly designed, it should help the loop track the 1pps signal
