Christian,
It looks like you are making some progress. One thing to mention is that registers R46,...R55 that you mention read back wrong contain some LDO related bits and also register R52[7] is the R divider reset and register R52[6] is the n divider…
Part Number: LMX2492 Team,
Can you please help with the below questions?
The lower frequency limit of the Fin pin is 500 MHz according to the data sheet. Is this a hard limit? Does the input still work below 500 MHz? Or is it just not specified for frequencies…
Part Number: LMX2492 Dear team,
Following is the configuration requirement from my customer:
1.there are 3 ramps in one chirp, ramp1:1500M-1505M, 15us, ramp2:1505M-1500M, 19us, ramp3: 1500M CW, 5us
2. Ramp is triggered by MOD pin
2. Ramp1 trigger a flag…
Hi Szczepan,
Your test result proved that the combination of DEN, NUM and modulator order matches the theory. When NUM/DEN = 1/2, there is no randomization at all, so the phase noise is good but spur is high. Different modulator order changes the phase…
Part Number: LMX2492 Dear TI support team,
here is an issue with the Charge Pump Voltage Monitor of the LMX2492.
Our design had used the CPMON functionality for lock detection by assigning the "CPMON good" signal to the TRIG2 output. This has always worked…
Part Number: LMX2492 I would like to verify that CSR will work with my application. I'm using 3.1mA of charge pump current. If I select x4 for FL_CSR, the charge pump current , R and N should increase 4x. Does the LMX2492 have the capability to increase…
Part Number: LMX2492 Hi, I currently have managed to generated a 9 to 10ghz chirp (1ghz bandwidth) using the lmx2492EVM.
I'm wondering if it is possible to generate a 6ghz to 7ghz chirp instead by just modifying the TICS pro
software configuration…
Part Number: LMX2492 Hi Team
I'm going to use the LMX2492 in an application where I frequently disable the device using the CE pin. When the part is re-enabled do the registers maintain their last programmed state? ie are the registers non-volatile…
Part Number: LMX2492 Other Parts Discussed in Thread: LMX2594 Hello,
we use the LMX2492 to generate a frequency sweep using an external ramp increment clock and ramp trigger. For our application it would be advantageous if a ramp that gets triggered again…
Part Number: LMX2492 Hi, I'd like to use the LMX2492 in a chirp radar. To enhance Tx/Rx isolation ; I'll need to switch off my Tx PA and the diplexer between PA/LNA/Antenna. The PA needs some time (~500ns) to get to its nominal output power and…
