14.2
14.2.1
The PIC16F627A/628A/648A can be operated in eight
different oscillator options. The user can program three
configuration bits (FOSC2 through FOSC0) to select
one of these eight modes:
• LP
• XT
• HS
• RC
• INTOSC Internal Precision Oscillator (2 modes)
• EC
14.2.2
In XT, LP or HS modes a crystal or ceramic resonator
is connected to the OSC1 and OSC2 pins to establish
oscillation (Figure 14-1). The PIC16F627A/628A/648A
oscillator design requires the use of a parallel cut
crystal. Use of a series cut crystal may give a frequency
out 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 (Figure 14-4).

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 compo-
nents.
Higher capacitance increases the stability
of the oscillator, but also increases the
start-up time. These values are for design
guidance only. A series resistor (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 manufac-
turer for appropriate values of external
components.
