3.5 External Clock Operation
The 56F805 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.
3.5.1
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. In Figure 3-7 a recommended crystal
oscillator circuit is shown. 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 56F80x
oscillator circuitry is designed to have no external load capacitors present. As shown in Figure 3-8, 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
