1. When only an individual single-ended clock output is required, tie OUT# and OUT#b together.
2. Analog power plane should be isolated from a 3.3V power plane through a ferrite bead.
3. Each power pin should have a dedicated 0.01F de-coupling capacitor. Digital VDDs may be tied together.
4. Unused clock inputs (REFIN or CLKIN) must be pulled high or low - they cannot be left floating. If the crystal oscillator is not used, XOUT must be left floating.
