External Clock Source
To clock the AS3930 with an external signal the crystal oscillator has to be enabled ( R1<0> =1). As shown in Figure 3 , the clock must be applied
on the pin XIN while the pin XOUT must stay floating. The RC time constant has to be 100 μ s with a tolerance of ±10% (e.g. R=680 k Ω and
C=22pF). In Table 25 , the clock characteristics are summarized.
