Auxiliary Synthesizer Registers
The Auxiliary Divider Register contains the integer portion closest
to the desired fractional-N (or integer-N) value minus 32 for the
auxiliary synthesizer. This register, in conjunction with the
Auxiliary Dividend Register (which controls the fraction offset from
–0.5 to +0.5), allows selection of a precise frequency. As shown
in Figure 9, the value to be loaded is:
Auxiliary Synthesizer Divider Index = Nine-bit value for the integer
portion of the auxiliary synthesizer dividers. Valid values for this
register are from 6 to 505 (fractional-N) or from 0 to 511 (integer-
N).The Auxiliary Dividend Register controls the fraction part of the
desired fractional-N value and allows an offset of –0.5 to +0.5 to
the auxiliary integer selected through the Auxiliary Divider
Register. As shown Figure 10, the value to be loaded is:
Auxiliary Synthesizer Dividend = Ten-bit value for the auxiliary
synthesizer dividend.
General Synthesizer Registers
The dual-programmable reference frequency dividers provide the
reference frequencies to the phase detectors by dividing the
crystal oscillator frequency. The lower five bits hold the reference
frequency divide index for the main phase detector. The next five
bits hold the reference frequency divide index for the auxiliary
phase detector. Divide ratios from 1 to 32 are possible for each
reference frequency divider (see Tables 2 and 3).
The Reference Frequency Dividers Register configures the dual-
programmable reference frequency dividers for the main and
auxiliary synthesizers. As shown in Figure 11, the values to be
loaded are:
Main Reference Frequency Divider Index = Desired main
oscillator frequency division ratio –1. Default value on power up
is 0, signifying that the reference frequency is not divided for
the main phase detector.
Auxiliary Reference Frequency Divider Index = Desired auxiliary
oscillator frequency division ratio –1. Default value on power up
is 0, signifying that the reference frequency is not divided for
the auxiliary phase detector.
