Part Number: LMX2820 Currently I'm struggling to change the frequency on the LMX2820 via a FPGA. I'm able to do the default setup on the PLL and get it too lock and output the default frequency of 13.05 GHz. But when only changing the frequencies by updating…
Hi Aathimoolam,
What about LD pin? Is the LD pin high even if OSCin is removed? LD is a more reliable indicator of lock status for LMX2820 instead of rb_LD.

Part Number: LMX2820 Hi Team:
In our design, Use 1 set of SPI bus to configure 2 piece of LMX2820;
just with CS pin as a distinction. but we found the mcu is can't read the correct information, because the MUXOUT(MISO) pin is 2V;
so how can we…

Hi
I am using LMX2820 on custom board and I am using TI eval board to configure the device.
I am able to read and write the data to LMX2820, but I am not finding any Vtune voltage. Can anyone help…
Part Number: LMX2820 Hi Team,
My customer would like to confirm if LMX2820 below pins are not use can they connect to ground through capacitor and resistors?
RFIN 、 RFDIN 、 SRREQ 、 RFOUT 、 SROUT
Thanks

Part Number: LMX2820 I'm using the Mute pin for pulse modulation.
The time spec for Mute/Unmute is 200nSec.
When I set Mute pin to 3.3V the signal is muted in less than 200nSec which is good.
However, when changing it back to Mute = 0V, for frequencies…
Part Number: LMX2820 Hi,
I am trying to set the phase angle between the reference input and output to 270 degrees. I've been playing around with the evaluation board and it seems like that only way I can achieve this is by toggling the PSYNC pin. The…

Hi,
I used LMX2820 to output signals from 7000MHz to 13200MHz in 2MHz steps. I test it a few times, and occasionally there was a unlock issue(bit 15-14 of R74 is 0x3,not 0x2), which was at 11310 and 12652MHz respectively. LMX2820…
Part Number: LMX2820 Other Parts Discussed in Thread: USB2ANY , MSP-EXP430FR6989 , LMX2594 Hi,
I'm using the LMX2820EVM, and testing with two different setups:
Setup 1: TICS Pro / USB2ANY / LMX2820EVM
Setup 2: MSP-EXP430FR6989 w/ custom SW / LMX2820E…
