Integrated Circuits (ICs)

RF synthesizerfractional-N PLLFSKintegrated VCOWQFN-36

LMX2571NJKR is a 36-pin RF fractional-N synthesizer for 10 MHz to 1344 MHz outputs using its integrated VCO, with direct digital FSK and external-VCO PLL capability.

Best for

  • Low-power RF local oscillators
  • FSK-capable radio synthesizers
  • Duplex TX/RX frequency switching

Avoid if

  • A simple fixed-frequency oscillator is sufficient
  • The design cannot support PLL loop-filter development

Check before use

  • Integrated-VCO output range of 10 MHz to 1344 MHz
  • Reference input and phase-detector frequency limits
  • External-VCO supply and loop-filter requirements
