Block Diagram

DS012806-3

Note: The RF prescaler for the LMX2331L/32L is either 64/65 or 128/129, while the prescaler for the LMX2330L is 32/33 or 64/65.

Note: VCC1 supplies power to the RF prescaler, N-counter, R-counter and phase detector. VCC2 supplies power to the IF prescaler, N-counter, phase detector,

R-counter along with the OSCin buffer, MICROWIRE, and FoLD. VCC1 and VCC2 are clamped to each other by diodes and must be run at the same voltage level.

Note: VP1 and VP2 can be run separately as long as VP ≥ VCC.
