LMX2372 Datasheet Dual Frequency Synthesizer

Manufacturer: National Semiconductor (now Texas Instruments)

Overview: LMX2370/LMX2371/LMX2372 PLLatinum Dual Frequency Synthesizer for RF Personal Communications PRELIMINARY March 1999 LMX2370/LMX2371/LMX2372 PLLatinum™ Dual Frequency Synthesizer for RF Personal Communications LMX2370 LMX2371 LMX2372 2.5 GHz/1.2 GHz 2.0 GHz/1.2 GHz 1.2 GHz/1.2 GHz The LMX237X are available in a 24-pad chip scale (CSP) or a 20-pin TSSOP surface mount plastic package.

General Description

The LMX237X family of monolithic, integrated dual frequency synthesizers, including prescalers, is designed to be used as a first and second local oscillator for dual mode or dual conversion transceivers.

It is fabricated using National’s 0.5u ABiCV silicon BiCMOS process.

The LMX237X contains two dual modulus prescalers.
