3V3
Power
The 3.3V can be continuously supplied or
only when the WAKE pin is asserted “high”.
This power domain is high power (internal
CPU, Transceiver, and RF PA) and should
be decoupled with a low ESR, high
capacitance Capacitor.
9
TOUT
Output
TOUT is a normally low signal that pulses
high in response to specific Network Timing
Events.
10
TIME_QUAL
Output
This pin is used by the Extender for Node-
based timing derivation.
