LPC11U2x
32-bit ARM Cortex-M0 microcontroller
In slave mode, couple the input clock signal with a capacitor of 100 pF (Figure 29), with an
amplitude between 200 mV (RMS) and 1000 mV (RMS). This signal corresponds to a
square wave signal with a signal swing of between 280 mV and 1.4 V. The XTALOUT pin
in this configuration can be left unconnected.
External components and models used in oscillation mode are shown in Figure 30 and in
Table 18 and Table 19. Since the feedback resistance is integrated on chip, only a crystal
and the capacitances CX1 and CX2 need to be connected externally in case of
fundamental mode oscillation (L, CL and RS represent the fundamental frequency).
Capacitance CP in Figure 30 represents the parallel package capacitance and must not be
larger than 7 pF. Parameters FOSC, CL, RS and CP are supplied by the crystal
manufacturer.
