Potential current peak in radio transceiver state SLEEP
Potential long PLL settling duration
When leaving active states like receive or transmit immediately towards SLEEP
state, a transient current peak of a few µA at DEVDD may occur for a short
period of time. Occurance depends on operational parameters as well as load
capacitance at pin 29 (AVDD).
Problem Fix/Workaround
Place an external resistor (for example 220kΩ) between AVDD and AVSS, in
parallel to the AVDD load capacitor.
In very rare cases a PLL_LOCK interrupt is not generated within the specified
maximum t
Problem Fix/Workaround
In such a case perform the following action:
-
-
-
-
read the register bits PLL_CF (register 0x1A, PLL_CF)
invert the LSB bit
write the value back to the PLL_CF register; keep upper four bits as
read before
wait a additional typical t
generated
PLL_INIT
= 250µs PLL lock duration.
PLL_INIT
= 80µs duration or until interrupt is
