Part Number: LMX2581EVM Other Parts Discussed in Thread: LMX2581E Hi, I am working on schematic capture for LMX2581E but has several questions. My reference schematic is figuure 8 at snau136c.pdf
1) RF output pull up: RF output As used 51ohm resistor…
Part Number: LMX2581E Hi all,
According to the LMX2581E datasheet, there are two powerdown modes, Partial Powerdown and Full Powerdown. Which powerdown state is IccPD? When coming out of a partial powerdown state, how long will the VCO be operarional…
Other Parts Discussed in Thread: LMX2581E Hello,
The LMX2581E has 4 VCOs core frequency to program in the PLL depending on the application.
Unfortunately we do not see a curve of the dependence between the frequency range and the voltage controlled…
Hi Noel,
First, my ultimate application is using 4 different clocks for four ADC cards to be applied for specific application. Before I do 4 different clocks, I tried 4 identical clocks with 4 sets of LMX2581E EVB to see if there is any phase jitters…
Hi Laxmi,
Thanks for contacting TI. If you look on the Quality & Packaging tab for this part, you'll find that you can download a .bxl file and translate it to one of the supported CAD tools. Altium is one of the supported tools. Please refer to for…
Thank You Noel. Done with designing.
Few more things I wanted to confirm.
1. Can I change the frequency of VCO in runtime to sweep the transmitting frequency? Let's say 2.8GHz to 3.4 GHz sweep. Basically, I am trying to convert doppler design in FMCW…
Other Parts Discussed in Thread: LMX2581E , LMX2581 Hi, everybody I had used LMX2581E in my project.
The reference fsoc is 20.000MHz/1ppm. And the pase frequency is 20MHz.
I had divide the vco output from 50MHz~1000MHz,1KHz each step. When I changed…
Other Parts Discussed in Thread: LMX2581E Hi,
I would like to use LMX2581E eval board around 8 units for generating different output frequencies for my system. I found in manual, I can set output frequency through computer interface. If I want to set…
Other Parts Discussed in Thread: LMX2541 , LMX2581E , LMX2581 Hi,
I would like to ask you a question about the difference between LMX2581 and LMX2581E and LMX2541.
I think those devices are very similar and the difference is VCO range, PLL noise and…
