LMX2531

High Performance Frequency Synthesizer System with

Integrated VCO

General Description

Features

The LMX2531 is a low power, high performance frequency

synthesizer system which includes a fully integrated delta-

sigma PLL and VCO with fully integrated tank circuit. The third

and fourth poles are also integrated and also adjustable. Also

included are integrated ultra-low noise and high precision

LDOs for the PLL and VCO which give higher supply noise

immunity and also more consistent performance. When com-

bined with a high quality reference oscillator, the LMX2531

generates very stable, low noise local oscillator signals for up

and down conversion in wireless communication devices.

The LMX2531 is a monolithic integrated circuit, fabricated in

an advanced BiCMOS process. There are several different

versions of this product in order to accommodate different

frequency bands.
