4.5.1
The internal oscillator employs an external crystal con-
nected to the on-chip amplifier. The on-chip amplifier is
accessible on the X27I input and X27O output signals. See
Figure 4-3 for the recommended external circuit and Table
4-5 for a list of the circuit components.
Choose C
capacitance. The load capacitance C
is comprised of C
parasitic capacitance of the circuit. The parasitic capaci-
tance is caused by the chip package, board layout and
socket (if any), and can vary from 0 to 10 pF. The rule of
thumb in choosing these capacitors is:
