The LMX2353TMX/NOPB is a monolithic integrated fractional N frequency synthesizer designed for use in local oscillator subsystems for radio transceivers. It operates within a frequency range up to 2.5 GHz and is fabricated using a 0.5¬µ ABiC V silicon BiCMOS process. The device features dual modulus prescalers and supports modulo 15 or 16 fractional compensation circuitry in the N divider, allowing for flexible frequency generation. This synthesizer employs a fractional N phase-locked loop (PLL) technique to produce stable, low-noise control signals suitable for UHF and VHF voltage-controlled oscillators (VCOs). It includes a programmable charge pump with current levels adjustable from 100 ¬µA to 1.6 mA in 100 ¬µA steps, and two uncommitted CMOS outputs that can be configured for external control signals or FastLock,Ñ¢ mode. The LMX2353 operates with a supply voltage ranging from 2.7 V to 5.5 V, with a typical current consumption of 5.5 mA at 3.0 V. It is available in a 16-pin TSSOP or a 16-pin CSP surface mount package, making it suitable for compact designs in portable wireless communications, cellular systems, and cable TV tuners.
