Clock Generators, PLLs, Frequency Synthesizers Procurement Notes

Verify the exact suffix against official Texas Instruments documentation to confirm pinout and electrical specifications. Confirm moisture sensitivity level requirements during storage and handling. Ensure the ordering quantity matches the manufacturer's standard packaging units. Cross-reference the RoHS compliance status with current regulatory standards before finalizing procurement.

Clock Generators, PLLs, Frequency Synthesizers Selection Notes

Select this model when a fixed-frequency or narrow-bandwidth synthesizer near 1.77 GHz is required. Compare power consumption and phase noise performance against other LMX2531 variants if broader tuning ranges are needed. Verify that the 36-WQFN footprint fits the target PCB layout constraints. Check thermal dissipation capabilities given the 32 mA operating current.

Clock Generators, PLLs, Frequency Synthesizers Part Context

This component belongs to the LMX2531 family of high-performance PLL frequency synthesizers. The 'LQ' designation typically indicates a specific factory configuration or band optimization within the series. Other variants like LMX2531LQ2820E/NOPB share similar architectural features but differ in tuned frequency bands. The NOPB suffix denotes lead-free and RoHS-compliant construction.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

LMX2531LQ1146E/NOPB offers a lower frequency center point. LMX2531LQ2820E/NOPB targets higher frequency bands. Direct substitution requires verifying register settings and loop filter components match the new variant's optimal performance curves.
