Figure 54. Crystal oscillator and resonator connection diagram
Table 101. Negative resistance (absolute min. value @125
The given values of C
printed circuit board: The negative resistance values are calculated assuming additional
5 pF to the values in the table. The crystal shunt capacitance (C
stray capacitance between XTAL1 and XTAL2 pins is globally assumed equal to 4 pF.
The external resistance between XTAL1 and XTAL2 is not necessary, since already present
on the silicon.
