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

capacitor to ground C
mode, a minimum of 200 mV (RMS) is needed. For more details see the LPC2101/02/03
User manual UM10161 .
