Part Number: LMX2820 Tool/software: Hi,
As shown in the topology below, the LMX2820 works in Cat.3 synchronization mode. Whether to support the phase alignment of the output clocks of two chips, the error phase between the two outputs is fixed.
There…
Part Number: LMX2820 Tool/software: Hi Team,
I'm using the LMX2820 PLL IC on my board and interfacing it with USB to Any. I’ve connected a 10-pin ribbon cable on one side (to USB to Any) and a micro-D connector on the other. While the device is detected…

Hi:
We are using LMX2820 to generate 13-20GHz signal,
In some frequency bands, the chip may lose lock if the same parameter ( 2_b Change frequency operation as described below)is configured multiple times. For example…
Part Number: LMX2820 Tool/software: Hi,
As shown in the figure below, when doing instant calibration, does the output frequency of STEP 4 have to be 5.65GHz? Is 18.4GHz okay?
Thanks!
Part Number: LMX2820 Tool/software: I am seeing the LMX2820 unlock at some frequencies when performing a random tuning test. We know there is a problem with the doubler in autocal so at the moment we stick with frequencies that don't need the doubler…
Part Number: LMX2820 Tool/software: hi,
if anyone is interested in a linux driver for the lmx2820 evaluation module, I have a working driver.
The code was derived from this: https://forums.raspberrypi.com/viewtopic.php?t=319702 ,
I added the missing pieces…
Part Number: LMX2820 Tool/software: I have been using PLLatinum sim to tune the loop filter for the LMX2820 device, and the current configuration I have set up is telling me the loop bandwidth is ~30kHz. My question is: for the loop bandwidth, what is…
Part Number: LMX2820 Tool/software: Hi
I understand that if I use external mixer to down convert the PLL output into the PFDin, I can ignore 20LOG(N) when calculating the flat noise.
My question is how is the LO phase noise in the input of the mixer affects…
