LMX2350/LMX2352 PLLatinumTM Fractional N RF / Integer N IF Dual Low Power Frequency Synthesizer PRELIMINARY June 1999 LMX2350/LMX2352 PLLatinum™ Fractional N RF / Integer N IF Dual Low Power Frequency Synthesizer LMX2350 2.5 GHz/550 MHz LMX2352 1.2 GHz/550 MHz General Description The LMX2350/2352 is part of a family of monolithic integrated fractional N/ Integer N frequency synthesizers designed to be used in a local oscillator subsystem for a radio transceiver. It is fabricated using National’s 0.5µ ABiC V silicon BiCMOS process. The LMX2350/2352 contains dual modulus prescalers along with modulo 15 or 16 fractional pensation circuitry in the RF divider. A 16/17 or 32/33 prescale...
