8.1 Free-Run Accuracy G.8262 Option 1 and Option 2

To meet this requirement, the free-run frequency will never exceed ±4.6 ppm with reference to a traceable Stratum-1 reference. This includes initial power-up or wherever there is not sufficient holdover history accumulated.

With the LMK5C33216 reference removed, the device was locked to the holdover reference upon power on reset until holdover history was available. The holdover reference selected was within ±4.6 ppm. The output clock from LMK5C33216 followed the holdover reference.
