PLL Mode
The system clock is derived from the oscillator clock, multiplied by the N factor, and
divided by the P and K factors. Both VCO bypass and PLL bypass must be inactive for
this PLL mode. The PLL mode is used during normal system operation. .
System Frequency Selection
For the XC886/888, the value of P is fixed to 1. In order to obtain the required fsys, the
value of N and K can be selected by bits NDIV and KDIV respectively for different
oscillator inputs. The output frequency must always be configured for 96 MHz.
Table 24
provides examples on how f
sys
= 96 MHz can be obtained for the different oscillator
sources.
Table 25
shows the VCO range for the XC886/888.

Figure 26
shows the recommended ceramic resonator circuitry. When using an external
resonator, its frequency can be within the range of 3 MHz to 12 MHz. A resonator load
circuitry must be used, connected to both pins, XTAL1 and XTAL2. It normally consists
of two load capacitances C
1
and C
2
, and in some cases, a feedback (R
f
) and/or damp
(R
d
) resistor might be necessary.
