Apply multiple different capacitors for different frequency range on decoupling circuits. Each capacitor has different ESL, capacitance, ESR and different frequency response.
Avoid long traces close to radiation components and place them into an internal layer. It is preferred to have grounding shield and add a termination circuit at the end of long traces.
Do NOT use a ferrite bead or a resistor with a value of 3-Ω or larger resistor to connect between V33A and V33D.
Avoid negative current/negative voltage (–0.3 V) on all pins. Avoid voltage spikes of more than 3.8V on all pins. Schottky diodes may be required to clamp the voltage on any pins that could have voltage spikes during surge tests. Note that Schottky diodes have relatively higher leakage current, which can affect the voltage sensing at high temperature.
If the bias supply to the device is a switching supply, ripple should be
minimized. The higher the peak-to-peak magnitude and frequency of the ripple,
the more the oscillator frequency changes.
