LMX2353 Overview
The LMX2353 is a monolithic integrated fractional N frequency synthesizer, 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 LMX2353 contains dual modulus prescalers along with modulo 15 or 16 fractional pensation circuitry in the N divider.
