LMX2330LTM/NOPB

Clock Generators, PLLs, Frequency Synthesizers Overview

The LMX2330LTM/NOPB is a dual PLL frequency synthesizer IC from Texas Instruments, designed for high-performance clock generation. It operates within a supply voltage range of 2.7V to 5.5V and supports input frequencies up to 1.1GHz. The device features a 3:1 input-to-output ratio and utilizes CMOS logic levels for both input and output interfaces. Housed in a 20-TSSOP package with a width of 4.40mm, it is rated for operation across an extended temperature range of -40°C to 85°C. This component belongs to the PLLatinum series and includes one functional circuit per unit.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

This component is officially classified as obsolete by Texas Instruments and is no longer manufactured. Verification of availability should focus on distributor surplus stock or authorized secondary market sources rather than direct factory orders. Ensure that any sourced units are genuine and match the specific suffix requirements for lead-free compliance and RoHS standards before integration into production designs.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Engineers requiring this specific dual-synthesizer topology must evaluate alternative components due to the part's discontinued status. Selection criteria should prioritize devices offering comparable input frequency limits and dual-channel independence. Verify that replacement options support the required 20-TSSOP footprint or accommodate necessary PCB layout modifications if pinouts differ. Confirm that new selections maintain compatibility with existing system voltage rails and thermal constraints.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The LMX2330LTM/NOPB is part of Texas Instruments' PLLatinum family, which targets precision timing applications. As a dual synthesizer, it provides two independent frequency outputs from a single reference, reducing board space compared to using separate single synthesizers. Its design emphasizes low phase noise and flexible programming options for communication systems requiring precise clock alignment.
