LMX2330USLBX

Clock Generators, PLLs, Frequency Synthesizers Overview

The LMX2330USLBX is a PLLatinum low-power dual frequency synthesizer manufactured by Texas Instruments. Designed for RF personal communications, it integrates two independent phase-locked loops within a single package to support complex multi-standard applications. The device operates on a supply voltage ranging from 2.7 V to 3.6 V and functions reliably across an industrial temperature range of -40°C to +85°C. It utilizes a compact 24-pin TSSOP surface-mount package to minimize board space requirements while maintaining high performance in portable wireless systems.
