3.6 External Clock Operation
The 56F826 system clock can be derived from a crystal or an external system clock signal. To generate a
reference frequency using the internal oscillator, a reference crystal must be connected between the
EXTAL and XTAL pins.
3.6.1
Crystal Oscillator
The internal oscillator is also designed to interface with a parallel-resonant crystal resonator in the
frequency range specified for the external crystal in
Table 3-9
.
A recommended crystal oscillator circuit
is shown in
Figure 3-9
. Follow the crystal supplier’s recommendations when selecting a crystal, because
crystal parameters determine the component values required to provide maximum stability and reliable
start-up. The crystal and associated components should be mounted as close as possible to the EXTAL
and XTAL pins to minimize output distortion and start-up stabilization time.The internal 56F82x
oscillator circuitry is designed to have no external load capacitors present. As shown in
Figure 3-9
,
no
external load capacitors should be used.
The 56F80x components internally are modeled as a parallel resonant oscillator circuit to provide a
capacitive load on each of the oscillator pins (XTAL and EXTAL) of 10pF to 13pF over temperature and
process variations. Using a typical value of internal capacitance on these pins of 12pF and a value of 3pF
