Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the specific suffix NOPB indicates lead-free and RoHS compliance status as per manufacturer documentation. Confirm the TSSOP-16 package dimensions match your PCB footprint requirements. Ensure the supply voltage range aligns with your system's power rails. Check for any recent product change notifications regarding pinout or electrical characteristics before finalizing procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this component when a single-channel frequency synthesizer is required with a maximum output of 2.5 GHz. Consider the 16-TSSOP package if space constraints favor surface-mount technology over through-hole options. Evaluate the 2.8 mA current consumption against your total system power budget. Verify that the CMOS output drive capability meets the load requirements of downstream stages without additional buffering.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This part belongs to the LMX2340 series of PLLatinum frequency synthesizers. It shares architectural similarities with other members like the LMX2430 but differs in channel count and maximum frequency specifications. The LMX2347TM/NOPB represents a cost-effective solution for single-loop applications where high integration and moderate speed are prioritized over multi-synthesizer complexity.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements may include other single-loop PLL synthesizers from Texas Instruments such as the LMX2347M variant, though packaging differences must be verified. Cross-reference with LMX2340 series components for functional compatibility. Ensure substitute parts meet the same 2.5 GHz maximum frequency and 16-TSSOP package constraints.
