AVCC
AVEE
Connect to low noise or filtered 3.3V supply through a ferrite bead (600 Ω at 100
MHz: Murrata BLM31B601S or equivalent). Provide dual local HF bypassing to
AVEE (0.1 µf, 100 pf) for low inductance and resistance. A single low inductance
0.1 µf capacitor can be substituted for the pair (Vishay VJ0612 or equivalent,
< 0.5 nH max inductance).
ANALOG
Connect to ground plane.
Provide low impedance connection to 3.3V. Provide dual local bypassing to GND
ECLIOVCC plane (0.1 µf and 100 pf in parallel, or a single low inductance Vishay VJ0612 or
equivalent 0.1 µf cap).
