Hello,
I'm also studying LMX2485E using LMX2487E-EVM & TICS Pro.
(I use the VCO of other board for LMX2485E, not VCO of LMX2487E-EVM.
I select LMX2485E device mode of TICS pro.)
I found that TICS Pro LMX2485E mode has the following problems;
1) It does not write Resistor value of ONLY "RF Divider R value" of PLL mode.
Command of Only "RF Divider R value" is not come up in the command prompt of PLL mode.
It can write Resistor on "RF Divider R value" of User Control and Raw resistors mode.
2)When I select Prescalar=8 in PLL mode, actual Fvco frequency is not as calculated value.
CPOUTRF voltage is incorrect??
When I select Prescalar=16 is OK.
Please let me know how to solve the problems.

Hi Noel san,
Thanks for reply. OK. For now, I use LMX2487E.zip. Also, I'm waiting for your reply.
It has so many bugs :(
Thanks, Shoko
Hello Hi Sakaguchi-san,
We'll keep you updated on the progress. Were there any other bugs you experienced beyond the two you listed above?

Hi Noel san,
Thank you for zip file. But PLL is always unlock state when I use the zip file.
Did you confirm behavior using LMX2485-EVM?
Thanks, Shoko
Hello Timothy,
I have not found other bug yet.
If I have find any other bugs, I will let you know.
Didn't you check bug of TICS Pro's?

Hi Noel san,
I think the unlock is due to software.
Because it is not occurred the unlock and it works correctly, when I use LMX2487E.zip in TICS Pro.
By the way, I have replaced LMX2487E with LMX2485E on LMX2487E-EVB and I use the VCO of the other board for LMX2485E, not VCO of LMX2487E-EVM.
Currently, I use LMX2487E.zip.
Thanks, Shoko
Hi Noel san,
Yes, I can make LMX2485E lock using LMX2487E.zip.
I attached the image of the configuration I tried.
