12. Application information
12.1 Suggested USB interface solutions
12.2 Crystal oscillator XTAL input and component selection
The input voltage to the on-chip oscillators is limited to 1.8 V. If the oscillator is driven by a
clock in slave mode, it is recommended that the input be coupled through a capacitor with
C
i
= 100 pF. To limit the input voltage to the specified range, choose an additional
capacitor to ground C
g
which attenuates the input voltage by a factor C
i
/ (C
i
+ C
g
). In
slave mode, a minimum of 200 mV (RMS) is needed.
