The LMX2531 is a low-power, high-performance frequency synthesizer system that includes a fully integrated Delta-Sigma PLL and VCO with fully integrated energy storage circuitry. The third and fourth poles are also integrated and also adjustable. In addition, integrated ultra-low noise and PLLs and VCOs are included, which give higher power immunity and consistent performance and high accuracy of LDO. When combined with a high-quality reference oscillator, the conversion of LMX2531 up and down wireless communication devices is stable and the noise is low local oscillator. The LMX2531 is a monolithic integrated circuit manufactured on an advanced BiCMOS process. This product is available in several different versions to accommodate different frequency bands.

The device is programmed to facilitate the use of the three-wire MICROWIRE Operating interface, down to 1.8 volts.

The supply voltage range is 2.8 to 3.2 volts. The LMX2531 is obtained in a 36-pin 6x6x0.8 mm lead-free lead-free lead frame package (LLP).
