Comments
When asserting pin 11 (SLP_TR) or TRX_CMD = TX_START
first symbol transmission is delayed by 16 µs delay (PLL
settling and PA ramp up)
PLL settling time from TX_BUSY to PLL_ON state
Using TRX_CMD = FORCE_TRX_OFF (see register 0x02,
TRX_STATE),
Not valid for SLEEP state
Valid for P_ON or SLEEP state
Using TRX_CMD = FORCE_PLL_ON (see register 0x02,
TRX_STATE),
Not valid for SLEEP, P_ON, RESET, TRX_OFF and *_NOCLK
Comment
Leaving SLEEP state, depends on crystal Q factor and
load capacitor
FTN tuning time fixed
Depends on external bypass capacitor at DVDD
(CB3 = 1 µF nom., 10 µF worst case), depends on V
Depends on external bypass capacitor at AVDD
