Capacitor values are for design guidance only.
These capacitors were tested with the crystals listed
below for basic start-up and operation. These values
are not optimized.
Different capacitor values may be required to produce
acceptable oscillator operation. The user should test

An external clock source may also be connected to the

FIGURE 2-2:

A Phase Locked Loop (PLL) circuit is provided as an
option for users who wish to use a lower frequency
crystal oscillator circuit, or to clock the device up to its
highest rated frequency from a crystal oscillator. This
may be useful for customers who are concerned with
EMI due to high-frequency crystals.
The HSPLL mode makes use of the HS Oscillator
mode for frequencies up to 10 MHz. A PLL then multi-
plies the oscillator output frequency by 4 to produce an
internal clock frequency up to 40 MHz.
The PLL is enabled only when the oscillator Configura-
tion bits are programmed for HSPLL mode. If
programmed for any other mode, the PLL is not
enabled.
