Can I use LMX2433 and LMX2541 for FM-CW

Other Parts Discussed in Thread: LMX2433, LMX2541, LMX2571

Could you let me know if LMX2433 and LMX2541 can be used for FM-CW?


  • Takahiro-san,Both of these devices can produce a continuous tone.
    If you want to modulate the tone for the LMX2433, you can modulate the input (Fosc), modulate the VCO (Fvco), or manually program the N divider in our value; there is no special feature to support the modulation.
    On the LMX2541, you can modulate the input or loop filter voltage. We also have FSK feature that allows one to modulate between two different frequencies with a pin.
    The LMX2571 has the most features and accomodations for modulation, so you might want to consider this if your frequency is 1350 MHz or less.
