Instructions
Connect to low noise or filtered +3.3 V supply through a ferrite bead (600Ω 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).

Connect to ground plane.
Provide low impedance connection to +3.3 V. Provide dual local bypassing to
ECLIOVCC GND plane (0.1 µf and 100 pf in parallel, or a single low inductance Vishay
VJ0612 or equivalent 0.1 µf capacitor).
