LMX2531LQX1500E/NOPB

Clock Generators, PLLs, Frequency Synthesizers Overview

The LMX2531LQX1500E/NOPB is a fractional-N phase-locked loop (PLL) frequency synthesizer with an integrated voltage-controlled oscillator (VCO), manufactured by Texas Instruments. It operates within an output frequency range of 553 MHz to 3.132 GHz and requires a supply voltage between 2.8 V and 3.2 V. The device draws a typical operating current of 32 mA and functions reliably across a temperature range from -40°C to +85°C. It is housed in a 36-pin WQFN package with an exposed pad, designed for surface-mount assembly.
