Oscillator Configurations
9.2.1
OSCILLATOR TYPES
The PIC16F630/676 can be operated in eight different
Oscillator Option modes. The user can program three
Configuration bits (FOSC2 through FOSC0) to select
one of these eight modes:
LP
Low-Power Crystal
XT
Crystal/Resonator
HS
High Speed Crystal/Resonator
RC
External Resistor/Capacitor (2 modes)
INTOSC Internal Oscillator (2 modes)
EC
External Clock In
9.2.2
CRYSTAL OSCILLATOR / CERAMIC
RESONATORS
In XT, LP or HS modes a crystal or ceramic resonator
is connected to the OSC1 and OSC2 pins to establish
oscillation (see Figure 9-1). The PIC16F630/676 oscil-
lator design requires the use of a parallel cut crystal.
Use of a series cut crystal may yield a frequency
outside of the crystal manufacturers specifications.
When in XT, LP or HS modes, the device can have an
external clock source to drive the OSC1 pin (see

Additional information on oscillator config-
urations is available in the PIC Mid-Range
Reference Manual, (DS33023).
Note
1:
See Table 9-1 and Table 9-2 for recommended
values of C1 and C2.
2:
A series resistor may be required for AT strip cut
crystals.

Note 1: Higher capacitance increases the stability
of the oscillator but also increases the
start-up time. These values are for design
guidance only. Since each resonator has
its own characteristics, the user should
consult the resonator manufacturer for
appropriate values of external
components.

Note 1: Higher capacitance increases the stability
of the oscillator but also increases the
start-up time. These values are for design
guidance only. Rs may be required in HS
mode as well as XT mode to avoid
overdriving crystals with low drive level
specification. Since each crystal has its
own characteristics, the user should
consult the crystal manufacturer for
appropriate values of external
components.
