Reference divider ratio
The reference divider ratio is set by 4 bits in the WRITE
mode, giving 16 different ratios which allow to adjust the
comparison frequency to different values, depending on
the compromise which has to be found between step size
and phase noise.
Table 8 shows the different dividing ratios and the
corresponding comparison frequencies and step size,
assuming the device is provided with a 4 MHz signal at
pin XTAL.
The dividing ratio of 24 is implemented to fulfil the UK-DTT
recommendation regarding offset frequency of
1
6
MHz.

Reference dividing ratios
Note
1.
Only valid when the IC is used with a 4 MHz crystal.
Charge pump current
The charge pump current can be chosen from 4 different values depending on the value of bits C1 and C0 in the I

C-bus
byte 4, according to Table 9.
