LMX2485ESQ/NOPB TI PLL Frequency Synthesizer | 24-WQFN (4x4) | 6.0 GHz, Low Phase Noise

Product Overview

The LMX2485ESQ/NOPB is a high-performance, low-power delta-sigma fractional-N PLL frequency synthesizer from Texas Instruments. It operates over a frequency range of 10 MHz to 6.0 GHz, making it suitable for a wide variety of RF and microwave applications. The device integrates a fully programmable delta-sigma modulator, a high-frequency phase detector, and a charge pump, enabling fine frequency resolution and low phase noise. Housed in a compact 24-pin WQFN (4x4 mm) package, it is ideal for space-constrained designs.
