LMX2581SQE/NOPB TI Clock Generator | 32-WQFN (5x5) | 3.8GHz, -162dBc/Hz

Product Overview

The LMX2581SQE/NOPB is a high-performance, wideband frequency synthesizer from Texas Instruments, designed for demanding RF applications. It integrates a low-noise phase-locked loop (PLL) with a voltage-controlled oscillator (VCO) covering a frequency range from 50 MHz to 3.8 GHz. The device features exceptional phase noise performance of -162 dBc/Hz at 100 kHz offset (800 MHz carrier) and supports both integer-N and fractional-N modes. Housed in a compact 32-pin WQFN (5x5 mm) package, it is ideal for space-constrained designs.
