can I use the LMX2492EVM to control an external RF switch (synced to the chirp generation), I don't see any normal digital or analog outputs via that evaluation board.

much thanks for your time.

Hi Ehud,

I don't quite understand your question, would you please describe a bit more in detail how are you going to use the EVM to control the switch?

Hi Noel,

thanks for your time.

suppose I am generating a train of chirps via the EVB and I want in between 2 chirps, within the quiet zone in a synced with the chirps, to control an external switch (or anything else for that matter) via a digital or analog output, is that possible with this EVB,?

Hi Ehud,

LMX2492 can generate two output flags to indicate the start/stop of a ramp, you may use them as the trigger sources for other controls.

See LMX2492 datasheet, section 9.2.5 and LMX2491 datasheet, section 8.2.10 for details.
