LMX2331UTM

Clock Generators, PLLs, Frequency Synthesizers Overview

The LMX2331UTM is a PLLatinum™ PLL frequency synthesizer IC manufactured by Texas Instruments. It operates with a maximum frequency of 2GHz and supports an output frequency of 600MHz, featuring a 3:1 input-to-output ratio. The device accepts CMOS or TTL inputs and provides CMOS outputs. It functions within a supply voltage range of 2.7V to 5.5V and is rated for operation between -40°C and +85°C. Packaged in a 20-TSSOP (0.173", 4.40mm width) surface-mount housing, this single-circuit component is currently classified as obsolete.

Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

This component is officially listed as obsolete by the manufacturer. Verification of availability should focus on secondary market distributors rather than direct manufacturer channels. Confirm RoHS compliance status, as the listing indicates non-compliance. Ensure the 20-TSSOP package dimensions match the target PCB layout constraints before procurement consideration.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this part only if legacy compatibility with the 20-TSSOP package and specific 2GHz/600MHz frequency parameters is required. Verify that the CMOS/TTL input interface aligns with the system logic levels. Consider the obsolete status when planning long-term production lifecycles, as replacement sourcing may be limited to surplus inventory.

Clock Generators, PLLs, Frequency Synthesizers Part Context

The LMX2331UTM belongs to the PLLatinum family of frequency synthesizers from Texas Instruments. This series is designed for applications requiring stable clock signals. The UTM suffix denotes the specific tape-and-reel packaging variant within the 20-TSSOP form factor, distinguishing it from other tube-packaged versions of the base LMX2331 model.
