Part Number:LMX2595EVM
Dear TI engineers,
I just bought an LMX2595EVM board, and I tested it at low frequency (100M, 200M, 300M and 400M). The waveform(200MHz) is shown in the figure attached. I don't think the waveforms are correct. I think the waveforms should be square or sine. Besides, with frequency increasing, the peak-peak voltage decreases a lot.
I also attached my circuit setups here. I wonder is there any problems of my board or my setups?
Thanks!
Jessie
