Part Number: LMX2571 Tool/software: I am having trouble loading phase noise data from the input source (OSC) noise "Load Data" selection. Is there a model file I can see? I keep getting unhandled exception errors every time I try to load a…
Part Number: LMX2571
Tool/software:
I am trying LMX2571 board from aliexpress
The ref freq is 100MHz and frequency out is 1.0GHz but the output is not fix
But floating in less 100hz range..
I checked the MUX out pin is being high so it means locked…

Tool/software:
I am trying LMX2571 aliexpress board and I got succeed on board osc(100MHz) make 1.0GHz out
So after than I try external refernce clk(10MHz)
But it show +-2.45KHz offset peaks(-33db from center) added a lot on my…
Part Number: LMX2571 Tool/software: Hi Team,
Customer found the LD pin keep low but the output freq look stable in below config, the fref=19.2MHz, Vpp=2.5V; And Fin=7dBm, Hdn>20dB;
Could u help review their config?

Part Number: LMX2571 Tool/software: Hi Team,
1. For the 5V power supply of Vcc, if the power supply voltage is lower than 5V, for example, around 4.3V, can the charge pump work normally? Which spec will be affected?
2. In external VCO mode, when switching…
Part Number: LMX2571 Hi there!!
I am going to use LMX2571 to make 100MHz from the source (10MHz).
And I will use the internal VCO. And I don't need Fast Lock function.
Since I only need 100MHz output.
In this case, do I leave FLOUT1, FLOUT2 open like…
Part Number: LMX2571 Tool/software: Hi Team,
Customer encountered a problem with the charge pump when using LMX2571. The specific situation is as follows: Register configuration process:
1. First configure all registers, and configure the pump current…
Part Number: LMX2571 Is there an equation or appnote that describes optimal tuning for the RFout network for open drain mode (LC pullup tuning network)
