LPC11U1x
32-bit ARM Cortex-M0 microcontroller
In slave mode the input clock signal should be coupled by means of a capacitor of 100 pF
(
Figure 28
), with an amplitude between 200 mV(RMS) and 1000 mV(RMS). This
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 29
and in
Table 18
and
Table 19
. Since the feedback resistance is integrated on chip, only a crystal
and the capacitances C
X1
and C
X2
need to be connected externally in case of
fundamental mode oscillation (the fundamental frequency is represented by L, C
L
and
R
S
). Capacitance C
P

Figure 29
represents the parallel package capacitance and should
not be larger than 7 pF. Parameters F

manufacturer.
