LMX2354 Datasheet Dual Low Power Frequency Synthesizer

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: 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.

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.

Key Features

  • very low current consumption; typically LMX2354 (2.5 GHz).
  • 7.0 mA. The LMX2354 are available in a 24-pin TSSOP surface mount plastic package and 24-pin CSP. Features n n n n n n n Pin compatible/functional equivalent to the LMX2350 Enhanced Low Noise Fractional Engine 2.7V to 5.5V operation Low current consumption LMX2354: ICC = 7 mA typical at 3V Programmable or logical power down mode: ICC = 5 µA typical at 3V Modulo 15 or 16 fractional RF N divider supports ratios of 1, 2, 3, 4, 5,.
