LMX2330A - Dual Frequency Synthesizer

Download the LMX2330A datasheet PDF. This datasheet also covers the LMX2331A variant, as both devices belong to the same dual frequency synthesizer family and are provided as variant models within a single manufacturer datasheet.

General Description

The LMX233xA family of monolithic, integrated dual frequency synthesizers, including prescalers, is to be used as a local oscillator for RF and first IF of a dual conversion transceiver.

It is fabricated using National’s ABiC IV silicon BiCMOS process.

The LMX233xA contains dual modulus prescalers.

LMX2330A/LMX2331A/LMX2332A PLLatinum Dual Frequency Synthesizer for RF Personal Communications May 1999 LMX2330A/LMX2331A/LMX2332A PLLatinum™ Dual Frequency Synthesizer for RF Personal Communications LMX2330A 2.5 GHz/510 MHz LMX2331A 2.0 GHz/510 MHz LMX2332A 1.2 GHz/510 MHz General Description The LMX233xA family of monolithic, integrated dual frequency synthesizers, including prescalers, is to be used as a local oscillator for RF and first IF of a dual conversion transceiver. It is fabricated using National’s ABiC IV silicon BiCMOS process. The LMX233xA contains dual modulus prescalers. A 64/65 or a 128/129 prescaler (32/33 or 64/65 in the 2.5 GHz LMX2330A) can be selected for the RF synthesizer and a 8/9 or a 16/17 prescaler can be selected for the IF synthesizer.
