Crystal Oscillator
XTAL1 and XTAL2 are input and output, respectively, of an inverting amplifier which can be
configured for use as an On-chip Oscillator, as shown in
a ceramic resonator may be used.
C1 and C2 should always be equal for both crystals and resonators. The optimal value of the
capacitors depends on the crystal or resonator in use, the amount of stray capacitance, and
the electromagnetic noise of the environment. Some initial guidelines for choosing capacitors
for use with crystals are given in
by the manufacturer should be used.
Figure 4-2.
The Oscillator can operate in three different modes, each optimized for a specific frequency
range. The operating mode is selected by CKSEL3..1 fuses or by CSEL3..1 field as shown in
