LMX2492: MUX state: Output RAMP_CNT Finished

Alessandro Belfiume
Prodigy 10 points
Part Number: LMX2492

I'd like to generate N waveform and Knowing when the PLL is finished,

without going to polling the RAMP_EN bit.

I have tried output muxing on TRIG1 pin the state "Output RAMP_CNT Finished" = Value 38.

During this test TRIG1_PIN is "Output PP"= Value 2

Apart that CodeLoader4 or TICS Pro doesn't allow to set this option (it is Reserved),

I have used the same this option writing the value 38 for TRIG1_MUX.

I have verified that this option works well only if I generate waveforms with only 1 segment,

with more than 1 segment the TRIG1 mux= Output RAMP_CNT Finished doesn't work well,

I'm wronging some setup ?

Regards,

Alessandro

    Alessandro,

    I see that the TICSPro calls state 38 "Reserved", but the datasheet says it "Output RAMP_CNT Finished". In this case, trust the datasheet, although we really haven't tested this state very thoroughly.

    So in summary, I think that likely this is just the way it is.
    Would it make sense to instead use "Ramp0 Active" or one of those states. We have tried these more thoroughly.

    Regards,
