LMX2352 Datasheet Dual Low Power Frequency Synthesizer

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: 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.

This datasheet includes multiple variants, all published together in a single manufacturer document.

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.

Key Features

  • very low current consumption; typically LMX2350 (2.5 GHz) 6.75 mA, LMX2352 (1.2 GHz) 5.00 mA at 3.0V. The LMX2350/2352 are available in a 24-pin TSSOP surface mount plastic package. Features n 2.7 V to 5.5 V operation n Low current consumption LMX2350: Icc = 6.75mA typ at 3v LMX2352: Icc = 5.00mA typ at 3v n Programmable or logical power down mode Icc = 5 µA typ at 3v n Modulo 15 or 16 fractional RF N divider supports ratios of 1, 2, 3, 4, 5, 8, 15, or 16 n Programmable charge pump current level.
