3.4. System Timing
The system timing for TX mode is shown in Figure 6. The figures demonstrate transitioning from STANDBY mode
to TX mode through the built-in sequencer of required steps. The user only needs to program the desired mode,
and the internal sequencer will properly transition the part from its current mode.
The VCO will automatically calibrate at every frequency change or power up. The PLL T0 time is to allow for bias
settling of the VCO. The PLL TS time is for the settling time of the PLL, which has a default setting of 100 µs. The
total time for PLL T0, PLL CAL, and PLL TS under all conditions is 200 µs. Under certain applications, the PLL T0
time and the PLL CAL may be skipped for faster turn-around time. Contact applications support if faster turnaround
time is desired.
