LMX2491RTWR TI PLL/VCO | 24-WQFN (4x5) | 6.4 GHz, -150 dBc/Hz

Product Overview

The LMX2491RTWR is a high-performance frequency synthesizer from Texas Instruments, combining a phase-locked loop (PLL) with an integrated voltage-controlled oscillator (VCO). It operates over a wide frequency range of 100 MHz to 6.4 GHz, making it suitable for demanding RF applications. The device features ultra-low phase noise of -150 dBc/Hz at 100 kHz offset (6 GHz carrier) and supports both integer-N and fractional-N modes. Housed in a compact 24-pin WQFN (4x5 mm) package, it is designed for space-constrained systems requiring high spectral purity.
