Part Number: LMX2492-Q1 Other Parts Discussed in Thread: LMX2492 Team,
We are trying to figure out if we can delay the output clock by up to 10ns. Can you advise?
Thank you.
Part Number: LMX2492 I have a self made LMX2492 PLL circuit that I cannot get to lock.
1. The SPI communication seems to work OK.
I send SWRST : 0x000204
I set POWERDOWN to "Power up, ignore CE" : 0x000201
I config MUXout_MUX to "output readback…
Part Number: LMX2492 Hello
I am considering the LMX2492 for an update to an existing design. I would like to use it for an FMCW that requires both a positive and negative ramp of the frequency. Can the LMX2492 do a negative ramp? If not, are there any…
Part Number: LMX2492 Other Parts Discussed in Thread: LMX2491 Dean,
I have finally written my own controller for the LMX2492. I can write to the device and read back correct values in the registers. I have the system connected to my Spectrum Analyzer…
Part Number: LMX2492 Hi,
I want to perform a linear FMCW sweep from 13.4 to 14.0 GHz using a 100 MHz reference (I can change the XO frequency if you have another recommendation).
When performing such a wide sweep across 5 integer boundaries can I expect…
Part Number: LMX2492 Dear All,
I have implemented a LMX2492 PLL IC in a custom made test board and I wanted to verify that the IC is correctly soldered and powered on, so I powered it on with a 3.3V power supple and I measured the current output of said…
Part Number: LMX2492 In terms of using the Fastlock feature, is this only controlled via SW (i.e., register writes)? Or, is HW control also possible?
If HW control is possible, are there any performance differences in terms of using HW v. SW control? …
Part Number: LMX2492 Dear all,
I am using a LMX2492 EVM board to test the performance of the PLL on my application. I am using an external reference clock instead of the provided clock to lock the PLL and an external VCO. I have followed the EVM reference…
Part Number: LMX2492 We have an issue with lmx2492:
We used to install 25MHz reference oscillators on our boards. With doubling reference frequency to 50MHz we obtained good phase noise.
Problems started when there was a need to use external reference…
