Oscillator Configurations

9.2.1

OSCILLATOR TYPES

The PIC16F716 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 (Figure 9-1). The
PIC16F716 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/CLKIN pin (Figure 9-2).

Note 1:

See Table 9-1 and Table 9-2 for 
recommended values of C1 and C2.

2:

A series resistor (RS) may be required.

RF varies with the crystal chosen.

Note

1:

These values are for design guidance only. 
See notes at bottom of page.

Note 1: Higher capacitance increases the stability

of the oscillator, but also increases the
start-up time. 

2: Since each resonator/crystal has its own

characteristics, the user should consult
the resonator/crystal manufacturer for
appropriate values of external
components. 

3: RS may be required to avoid overdriving

crystals with low drive level specification.

4: When using an external clock for the

OSC1 input, loading of the OSC2 pin
must be kept to a minimum by leaving the
OSC2 pin unconnected.
