Part Number: LMX2491 I am having trouble when I try to externally trigger LMX2491 ramps
A while ago we spun up an LMX2491 board and used it successfully. This board was configured to chirp continuously with a rising falling cycle of either 20/25 or…
Part Number: LMX2491 Tool/software: what is the recommended charge pump supply voltage when the charge pump voltage is reduced to 4.0V some of the parts are giving oscillations in some bands
Part Number: LMX2491 Tool/software: I am using LMX2491 With BGTMTR11
The o/p from MTR11 Used to compare is /16 of Fout , I am trying to understand the PLL-atinum Sim to fix the values of loop filter to work stable for the frequency range from 24 -24…
Part Number: LMX2491 Other Parts Discussed in Thread: LMX2492 Tool/software: Hello,
I am using LMX2491 Fractional N PLL to generate a ramp as part of a radar system.
The simplified block diagram is presented below.
As both LMX2491 and LMX2492…
Part Number: LMX2491 Tool/software: Hi support team all.
I have a question about FSK modulation settings.
Q1: I believe the way to disable FSK modulation is to set FSK_DEV_TRIG, as listed in Table 20 of the datasheet. Is this correct? The TICSPRO…
Part Number: LMX2491 Tool/software: I was working an jamming project where i generating
1. A ramp from 2.4 to 2.485 GHz with 0.1us time period
2 .A ramp from 5.725 to 5.85 GHz with 0.1us time period
are settings correct for the above output if not…
Part Number: LMX2491 Tool/software: Hi team,
customer used LMX2491 as FMCW modulation with below register configuration. The scanning frequency is from 1.5Ghz to 1.515625GHz. The issue is CPout=0V, and TRIG1 is high. And this is a occasional issue.…
Part Number: LMX2491 hello my name is ko.
I am following the example of a continuous serrated lamp.
LMX2491 RAMP operation is not working, so I am inquiring.
The settings are as follows.
R141 0x008D00 R140 0x008C0F R139 0x008BA0 R138 0x008A00…
Part Number: LMX2491 Tool/software: Hello,
My customer confirmed that PLL Lock is normal when REF=100MHz, PDF=1MHz, R=100 is set using the LMX2491 board they designed.
However, when REF=100MHz, PDF=100MHz, R=1 is set, PLL Lock is not worked.
Are…
Part Number: LMX2491 Tool/software: Hi,
Customer debugged LMX2491 and used TICS Pro to configure registers, which output a sawtooth wave of 24.05-24.11G. I tested the VTUNE pin with an oscilloscope and found that the sawtooth wave output was correct…
