Part Number: LMX2492 Other Parts Discussed in Thread: LMX2491 Hi team,
If I want to design a simple chirp signal, do I need to configure TRIG1_PIN、TRIG2_PIN、MOD_PIN、MUXout_PIN、TRIG1_MUX、TRIG2_MUX、MOD_MUX、MUXout_MUX ?
There is no such configuration in…
Part Number: LMX2492 I sometimes do not get repeatable spur behavior on the eval board while switching through a sequence of different settings for the FRAC_ORDER, FRAC_DITHER, FRAC_NUM, and FRAC_DEN.
When I return to my initial settings, the spur behavior…
Part Number: LMX2492-Q1 Hello,
I am working in a frequency synthesizer, and I'm trying to model its behaviour with ADS keysight. However, my results are not very accurate compared to real behaviour of the PLL.
Could you provide any aid in modeling…
Part Number: LMX2492 Hi,
Good Day. I have a customer who is working with LMX2492. Please see below his query for your reference. Thank you very much.
In the register R58[1] (RAMP_CLK) we can select an external clock (MOD bus) for the ramp increment. Is…
Part Number: LMX2492
I was investigating the fractional spurious level in PLL PlatinumSim, and noticed a correlation between the spurious level and the Fnum/Fden of the N Divider. It seems that the Sub Fractional Spurious level caused by MASH_Nonlinear…
Part Number: LMX2492 Other Parts Discussed in Thread: LMX2491 Is there a specific timing for LMX2492 after SWRST is set? How long should we wait until reset is done? After this do we need to proceed with clearing the SWRST bit? and then proceed with programming…
Part Number: LMX2492 Hi Texas Instruments,
I want to make 11GHz output on LMX2492 and external VCO, MAOC-009265-TR0500(VCO on LMX2492evm) or most of VCO on market have 12V Vtune, but CPout of LMX2492 is 5V. Therefore, I need an active loop filter.
I use…
Part Number: LMX2492 Dear TI support team, I'd like to follow up on the previous conversation about the lock detect by Charge pump monitoring on the LMX2492, two months ago handled by Noel.
From one batch of our PCBs, we did not get reliable behavior…
Part Number: LMX2492 Hi team,
One of our customers has the following needs:
Give Trig1、Trig2 or MOD pin a trigger signal of a rising edge, and then the chirp signal starts to be sent. The cycle of a chirp is 60us. I send the trigger signal every 100us…
