LMX2581SQ/NOPB TI PLL/VCO | 32-WQFN (5x5) | 50MHz-3.6GHz, -152dBc/Hz

Product Overview

The LMX2581SQ/NOPB from Texas Instruments is a high-performance, wideband frequency synthesizer with integrated VCO, covering a frequency range of 50 MHz to 3.6 GHz. It is designed for demanding applications requiring low phase noise and high flexibility. The device operates from a 3.3V supply and features a fractional-N PLL with programmable charge pump current and loop filter. The integrated VCO provides excellent phase noise performance of -152 dBc/Hz at 100 kHz offset (2.6 GHz carrier). The LMX2581 is available in a compact 32-pin WQFN (5x5 mm) package, making it suitable for space-constrained designs.
