Integrated Circuits (ICs)

6.4 GHzfractional-N PLLFMCW rampFSKPSKWQFN-24

LMX2491RTWR is a 6.4 GHz fractional-N RF PLL for external-VCO frequency synthesis and FMCW ramp generation in a 24-pin WQFN package.

Best for

  • External-VCO microwave PLLs up to 6.4 GHz
  • FMCW radar and programmable chirp generation
  • Applications requiring FSK or PSK modulation

Avoid if

  • A complete synthesizer with integrated VCO is required
  • No external loop-filter design capability is available
  • The VCO input frequency is outside 500 MHz to 6.4 GHz

Check before use

  • Verify Fin input level and AC-coupling network.
  • Keep VCC within 3.15 V to 3.45 V and VCP no higher than 5.25 V.
  • Validate loop bandwidth and lock behavior across the required sweep range.
