Reserved. Set to 000 for normal operation.
PLL mode select:
1 = Fractional mode selected.
0 = Integer mode selected.
Sets the 4 most significant bits of the fractional PLL divider ratio.
Sets bits 15 through 8 of the fractional PLL divider ratio.
Sets the 8 least significant bits of the fractional PLL divider ratio.
Programs the notch frequency of the internal tracking filter. Optimal values for notch
frequencies of 783MHz and 725MHz can be read from the ROM table entries. See the
Reading the ROM Table section.
Programs the tracking filter balun. Optimum values over frequency can be interpolated
from the ROM table entries. See the Reading the ROM Table section.
Reserved. Set to all zeros for normal operation.
