Product Number: FMCOMMS8

Software Version: Vivado 2021.2

Hi Team,

I'm using FMCOMMS8_ZCU102 setup. When I'm tuning two LO's sequentially for ORX1 of ADRV9009_c and ORX1 of ADRV9009_d using FHM GPIO Mode( TALISE_setFhmHop() API) and read back the LO's using TALISE_getFhmRfPllFrequency() API , Initially LO's were tuning properly in the run -time. After some time, suddenly I'm getting previously updated LO instead of currently updating LO. What could be the reason for this?

Thanks and Regards
Satish

Do you mean Tx1 of C_chip and Tx1 of d_chip? are you using the non-GPIO mode or GPIO mode?

Please refer to the below section for the software configuration for RF PLL frequency hopping.

are you using ORx as a receiver in this application and why are you changing the ORx_LO.

It is not recommended to use it as Rx and there are limitations, and multiple features aren't available that Rx supports.
