16.3 Low Power Oscillator (LPO)
The LPO is implemented as a ring oscillator structure. Frequency can be
controlled/trimmed by adapting the CCO bias current with lpo_trimm. Target is to achieve
a trimming accuracy of 2.5 % with a maximum of 8 trimm-bits for all PVT conditions taking
into account also the reference current variations.
With linear trimming behavior following relation is valid for the output frequency:
f_lpo fipo = fcenter + delta_f (80h lpo_trimm); with fcenter being the frequency for
lpo_trimm in the middle of the range (lpo_trimm = 80h) and delta_f being the trimming
step size which must be < 0.05
f_target (for 2.5 % accuracy).
Trimming will be done by a digital state machine which compares LPO-clock to a
reference clock. As reference the 13.56 MHz crystal clock is available. The LPO
frequency must be chosen such that a period of 1 ms (=1/1 kHz) can easily be generated
with a 2N-counter.
For trimming M periods of the reference clock need to be counted with M = round(13.56
M/f_lpo). A small systematic error due to rounding of M to an integer value is introduced.
This error is with 0.06 % much smaller than the targeted trimming accuracy of 2.5 %.
The LPO can be set to power down with input pin PDOWN/RESET.
