I'm not sure I understand how it is able to approach timing resolution comparable to that of the THS788 yet at a fraction of the power. The sample rate is evidently quite limited. Is this just a function of the ring oscillator duty cycle being much smaller?
Also, does anyone understand the reason behind the 12ns minimum measurement time? Cheers, - Ben
