LED frequency
The frequency of the LED output (pin1) is determined by the oscillator frequency.
Three modes of operation, each with its own frequency, are possible.

MOLLI pulse duration
The MOLLI output gives an output signal of four periods with a 50%
duty cycle. The duration of one period is determined by: 16/fs
Timing accuracy.
The timing accuracy depends on the accuracy of the on–chip
oscillator and on the external R and C components. The inaccuracy
of the on–chip oscillator is specified as maximum +/–7%. In most
cases the actual inaccuracy will be significantly lower. This depends
on the supply voltage as well as the value of the external
components.
Influence of Resistor value.
Low resistor values cause some spread because the RC
combination is biased by a 3–State push–pull output. The spread of
the Ron of the push–pull stage will contribute to the frequency
spread. When high–value resistors are used, any possible output
leakage of the not–selected 3–State outputs will cause a frequency
deviation. For these reasons, the resistor values must be within the
specified ranges.
Influence of supply voltage
The trip levels of the oscillator are fixed at 20% and 80% of Vcc. At
higher supply voltages the spread of the trip levels decreases in
greater proportion because the offset voltage remains constant, and
the propagation delay decreases. Furthermore, the Ron values of
the push–pull driving stage decrease at higher voltages.
