LMX2582RHAR +BOM

Description

The Texas Instruments LMX2582RHAR is a high-performance clock generator/frequency synthesizer in a VQFN-40 EP package. It offers industry-leading phase noise performance, with a VCO phase noise of -144.5 dBc/Hz at a 1-MHz offset for a 1.8-GHz output. The device features an output frequency range from 20 to 5500 MHz and supports fractional-N and integer-N modes. The LMX2582RHAR has dual differential outputs, programmable phase adjustment, charge pump current, and output power level. It also includes an SPI or uWire (4-wire serial interface) for easy configuration. The device operates from a single 3.3-V power supply and is suitable for applications requiring high-frequency clock generation with low phase noise.
