LMX2354 PLLatinum Fractional N RF/ Integer N IF Dual Low Power Frequency Synthesizer August 2001 LMX2354 PLLatinum Fractional N RF/ Integer N IF Dual Low Power Frequency Synthesizer LMX2354 2.5 GHz/550 MHz General Description The LMX2354 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 0.5 µ ABiC V silicon BiCMOS process. The LMX2354 contains quadruple modulus prescalers along with modulo 15 or 16 fractional pensation circuitry in the RF divider. The LMX2354 provides a continuous divide ratio of 80 to 32767 in 16/17/20/21 (1.2 GHz- 2.5...
