17. Recommended VDD Power Supply Filtering
Because of the internal bypass capacitance and voltage regulators, the external supply bypass requirements for
the Si5040 are minimal.

Note:
1. Place a .01 µF cap very close to each VDD pin
(12, 15, 27, 32) and place a single 0.1 µF cap
close to the Si5040.
2. No power sequencing is required.
