Its dual-frequency maximums — 5 GHz on the RF path and 2.5 GHz on the IF path — set the upper band for down-conversion in superheterodyne receivers or direct-RF synthesis in wireless infrastructure and test equipment. Surface-mount assembly with a 0.50 mm pitch; the narrow pad spacing requires a solder-mask-defined land pattern per the TI application note for QFN packages. ## Supply and signal interface The RF input is differential (Yes/No input:output), so the driving source — typically a VCO buffer or balun — must provide a differential signal; the CMOS output is single-ended and drives the downstream logic or divider chain. Three reference inputs feed two synthesizer paths (3:2 ratio), allowing independent LO generation for the RF and IF stages from a shared reference oscillator. Lifecycle status is Active per Texas Instruments, so the part remains a current-design choice with no NRND or EOL flags — no last-time-buy pressure for new BOMs.","metaTitle":"TI LMX2434SLEX/NOPB PLLatinum Frequency Synthesizer","metaDescription":"Texas Instruments LMX2434SLEX/NOPB PLLatinum frequency synthesizer, 5 GHz RF / 2.5 GHz IF max, 20-WFQFN.
