11. Oscillator Characteristics
XTAL1 and XTAL2 are the input and output, respectively, of an inverting amplifier that can be
configured for use as an on-chip oscillator, as shown in Figure 11-1. Either a quartz crystal or
ceramic resonator may be used. For frequencies above 16MHz it is recommended that C1 be
replaced with R1 for improved startup performance. Note that the internal structure of the
devices adds about 10 pF of capacitance to both XTAL1 and XTAL2. The total capacitance on
XTAL1 or XTAL2, including the external load capacitor (C1/C2) plus internal device load, board
trace and crystal loadings, should not exceed 20 pF. Figure 11-2, 11-3, 11-4 and 11-5 illustrate
the relationship between clock loading and the respective resulting clock amplitudes.
