Accuracy is as good as the time base, e.g. for a delay of 1 s using internal time base, the worst case error will be (2.5 ppm x 1 s) = 2.5 us. The accuracy can be greatly improved by locking the card to GPS/Cesium clock source through [White Rabbit](https://www.ohwr.org/project/white-rabbit/wikis/Description)</td>
