Divider
The mixer divider V is followed by a division-by-4-stage that generates 0°/90°/-90° LO
signals for the IMR mixer (90°/-90° mode to switch between upper or lower sideband
suppression in the IMR).
The main divider N can be operated in integer mode or in fractional mode. Three fraction
factors are programmable: 2, 3 and 6. A fractional compensation circuit is located at the
charge pump. The compensation acts for the low current only.
