Notes:
1. Higher PLL bandwidth settings provide smaller clock output wander with temperature gradient.
2. For reliable device operation, temperature gradients should be limited to 10 °C/min.
3. Telcordia GR-1244-CORE requirements specify maximum phase transient slope during clock rearrangement in terms
of nanoseconds per millisecond. The equivalent ps/µs unit is used here since the maximum phase transient magnitude
for the Si5364 (t_{PT_MTIE}) never reaches one nanosecond.
