LMX2594: Lock Detect During Ramp Function Use

Paris Ang

Part Number: LMX2594

Tool/software:

Hello,

Is is possible to confirm that the lock detect on the MUXout pin works when the LMX2594 is generating a triangular/sawtooth waveform via the ramping function?

Thanks

Hi Paris,

MUXOUT will not always stay HIGH during ramping, waveform will depend on the ramp configuration.

Hi Noel,

Thanks! Are there any particular ramp settings which mess with MUXout LD or is it just the nature of the function itself?

Hi Paris,

It is just the nature of the LD, because Vtune is changing during ramp, so the LD follows.
