Functional Description

Data Sheet

V1.0, 2011-02
The clock system provides three ways to generate the system clock:
PLL Base Mode
The system clock is derived from the VCO base (free running) frequency clock divided
by the K factor.
Prescaler Mode (VCO Bypass Operation)
In VCO bypass operation, the system clock is derived from the oscillator clock, divided
by the P and K factors.
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.
Table 19 shows the settings of bits OSCDISC and VCOBYP for different clock mode
selection.
Note: When oscillator clock is disconnected from PLL, the clock mode is PLL Base mode
regardless of the setting of VCOBYP bit.
System Frequency Selection
For the SAL-XC866, the values of P and K are fixed to “1” and “2”, respectively. In order
to obtain the required system frequency, fsys, the value of N can be selected by bit NDIV
for different oscillator inputs. Table 20 provides examples on how fsys =75MHz can be
obtained for the different oscillator sources.
