CMX940 Frac-N RF Synth with Integrated VCO

CML Micro's RF synthesizer features highly-configurable near-noiseless clock multiplier technology

Image of CML Micro CMX940 Frac-N RF Synth with Integrated VCOCML Micro's CMX940 is a low-power high-performance Frac-N PLL with fully integrated wideband VCO generating RF signals over a range of 49 MHz to 2040 MHz. A highly-configurable near-noiseless clock multiplier technology can be used to minimize close-in phase noise and mitigate integer and fractional boundary spurious. It has two level-controlled single-ended RF outputs to support Tx and Rx sub-systems.

Features
  • RF output frequency: 49 MHz to 2040 MHz
  • Low current consumption: ~58 mA
  • Supply voltage: 3.0 V to 3.6 V
  • Low 1 Hz normalized PLL noise floor of -225 dBc/Hz
  • Typical phase noise: -122 dBc/Hz, 10 kHz offset at 520 MHz
  • Dual programmable RF outputs
  • Low noise VCO: -141 dBc/Hz, 1 MHz offset at 520 MHz
  • Automatic VCO selection and calibration
  • 16-bit and 24-bit fractional-N PLL modes
  • High comparison frequency up to 120 MHz
  • Very fast frequency switching <50 µs
  • Low level of spurious products -75 dBc (typ.)
Applications
  • LMR/PMR
  • IIoT wireless data modems
  • VHF/UHF satcoms
  • Aviation radios
  • Marine radios
  • AIS/VDES marine data
  • Wireless microphones
  • Ham radios
