Part Number: LMX2491
Tool/software:
Hi,
Customer debugged LMX2491 and used TICS Pro to configure registers, which output a sawtooth wave of 24.05-24.11G. I tested the VTUNE pin with an oscilloscope and found that the sawtooth wave output was correct. I also tested the sweep range with a spectrometer, but the muxout (output DLD&CPMON OK) output remained at a high level of 3.3V and could not output a pulse signal to the MCU. Is this because the output pin status was set incorrectly? I tried output DLD OK, but OUTPUT ramp 0 active did not output a pulse signal. Could you please help me figure out ? Thank you!
