Table 6. FREQUENCY vs. OFFSET
*OS is the OFFSET default setting. OS is the integer value of the five MSBs of RANGE register.
These ranges include values outside the oscillator range of 33MHz to 66MHz. When using these ranges,
values of DAC must be chosen to keep the oscillator within range. Correct operation of the device is not
guaranteed outside the range 33MHz to 66MHz.
MUX WORD
The MUX word controls several functions. Its bits are organized as follows:
* This bit must be set to zero.
X = Don’t care.
NAME * PDN1 PDN0 SEL0
