Oscillator Configurations
9.2.1
OSCILLATOR TYPES
The PIC16CXXX can be operated in four different
Oscillator
modes.
The
user
can
program
two
Configuration bits (FOSC1 and FOSC0) to select one
of these four modes:
LP
Low-Power Crystal
XT
Crystal/Resonator
HS
High-Speed Crystal/Resonator
RC
Resistor/Capacitor
9.2.2
CRYSTAL OSCILLATOR/CERAMIC
RESONATORS
In XT, LP or HS modes, a crystal or ceramic resonator
is connected to the OSC1/CLKIN and OSC2/CLKOUT
pins
to
establish
oscillation
The
PIC16CXXX oscillator design requires the use of a par-
allel cut crystal. Use of a series cut crystal may give a
frequency out of the crystal manufacturers specifica-
tions. When in XT, LP or HS modes, the device can
have an external clock source to drive the OSC1/
CLKIN pin (Figure 9-3).

recommended values of C1 and C2.
2: A series resistor (RS) may be required for
AT strip cut crystals.

Note 1:
Recommended values of C1 and C2 are
identical to the ranges tested (Table 9-1).
2:
Higher capacitance increases the stability
of the oscillator, but also increases the
start-up time.
3:
Since each resonator/crystal has its own
characteristics, the user should consult
the resonator/crystal manufacturer for
appropriate values of external compo-
nents.
4:
Rs may be required in HS mode, as well
as XT mode to avoid overdriving crystals
with low drive level specification.
