Part Number: LMX2820 Tool/software: Dear Team,
I am using the LMX2820 PLL to generate various output frequencies with a 100 MHz reference frequency derived from a TCXO. I would appreciate it if you could provide the recommended TICS Pro GUI configuration…
Hi Eddie,
Total lock time = programming time + calibration time + analog lock time.
Right, analog lock time is proportional to the loop filter design.
User can shorten the programming time with higher SPI speed.
In LMX2820, calibration time can be eliminated…

Hi everyone,
I am working with LMX2820 PLL to generate 8.5 to 10.5 GHz using 120 MHz sine wave as input with +5 dBm input power. Generating 8.5072 GHz and observing spurious near the carrier and same…
Part Number: LMX2820 Tool/software: Hi everyone,
I am working with two LMX2820 PLLs that share common SPI lines, with only the chip select (CS) differentiating between PLL1 and PLL2. I am facing an issue where I am unable to generate different output…
Part Number: LMX2820
Tool/software:
Your spec. is 45MHz到22.6GHz....But I can't set RFOUT to 1 GHz from TICS PRO
How should I set on internal VCO? Or it's lowest at 5.65GHz ?
Part Number: LMX2820 Tool/software: Hi all,
The datasheet for the LMX2820 lists the max VOSCin differential input voltage as 1Vpp.
Is this the total differential swing allowed between pins?
There's a note "(6) See applications section for definition…
Part Number: LMX2820 Tool/software: Dear Team, I am using the LMX2820 PLL in my application to generate Ku-band single-tone signal. A clean and stable 100 MHz reference from TCXO is provided to the device. However, I am observing in-band spurious signals…
Part Number: LMX2820 Tool/software: Dear All,
I’m currently working with the LMX2820 in a specific design, aiming to achieve deterministic phase alignment every time the PLL locks to a given frequency. For instance, I would like the device to maintain…
Part Number: LMX2820 Tool/software: Hello,
LMX2820 still does not appear to have SPI timing diagrams in the publicly available datasheet. This was reported over a year ago and looks to still be unresolved. When will SPI timing diagrams get added back…
