Part Number: LMX2572 Other Parts Discussed in Thread: LMX2594EVM Hi, I am trying to do PLL lock using SPI thorugh STM microcontoller for LMX2572, i am facing an issue to lock PLL where i am using 125 MHz (Fosc) and trying to calibtrate the using the sequence…
Part Number: LMX2572 Hello,
Could someone from TI technical support please contact me via email? I do not want to post this on a public forum. Thank you!
Hi Noel,
have you heard back from the designers, with a suitable workaround that could avoid externally bypassing the LMX2572 with regards to SYSREF and hence requiring a board re-spin ?
Best regards

Part Number: LMX2572 Hi,
Does anyone know what the difference between LMX2572RHAT vs LMX2572RHAR is? Can't find anything on the DS and all I see is there they have different volumes and prices.
Thanks in advance for any help!
Part Number: LMX2572 I want too generate Ramp of 100 MHz with VCO free calibration and want to see this ramp in PLLatiunm Tool.
my PLL is getting locked but i am unable to see the ramp in the tool. please provide me guidance to generate a ramp.
Part Number: LMX2572 I am using PLLatinum Sim software for generating RAMP of 500 MHz in less then 20usec but i am not getting the option for setting ramp size please help.or share any video link if possible
Part Number: LMX2572 Hello, At LMX2572, to measure lock time (register setting complete to frequency lock) in full assist mode, measuring from CSB rising edge after writing VCO_DACISET register to MUXout edge (MUXOUT_LD_SEL = 1) is right method? If yes…
Hi Shuhei, The differences are due to corners - given this was simulated across PVT. In regards to frequency pushing, our device have internal LDOs thus your output won't vary - the internal LDOs will regulate the supply voltage to ensure it stays constant…

Part Number: LMX2572 Hello
I just want to confirm the technical solution with you since you are the experts.
Due to ppm stability ( +-25 ppm ) I have decided to go with LMK6210-100M, this device have HCSL output freq.
From my understanding the HCSL…
