But I make it 0.0083333 Hz resolution, (still OK nice value though) and can't be locked to a 1PPS signal. Better still, use it with an AD9851 chip using the x6 PLL multiplier for 50mHz steps.

I am using an AD9850 clocked with a 3579.545 kHz crystal pulled to 3579.1394 kHz. This allows integer resolution to 10 mHz. The results have been excellent, once I corrected a minor computational oversight!
