Different sampling rate for baseband rx and tx

HI olegeorg ,

No, we can only configure same sample rate.

Hi, 

Ok, thanks for confirmation. Do analog device offer other RF transceiver chip(s) that have similar performances as AD9361, but support my sampling rates requirement. 

Hi olegeorg ,

Please confirm your Tx and Rx bandwidth and no of channels requirement. are you looking for device supporting for external LO or internal LO.

This will help us to suggest suitable one for you.

Hi,

One Rx and Tx channel. I can use external LO if it is necesarry. Rx @305 MHZ and Tx @255 MHz. The sampling rate from the ADC to the FPGA must be 92.16 MSPS and the sample rate from the FPGA to the DAC must be 102.4 MSPS.

HI olegeorg ,

Thanks for the inputs. what is the bandwidth requirement in both Tx and Rx.

Regards,

SJ

Hi

30 MHz for both Rx and Tx. 

Do you know a transceiver that fits these requirements?

HI olegeorg 

As the sample rates are provided not regular one to use. 

AD9371 may be possible but request to check clock plan
or ADRV9009 is best suited one but still clock rate has to optimized.

Hi,

Do you think that AD9371 is the best options given that I need rx = 92.16 MSPS  and tx = 102.4 MSPS?


ADRV9009 support only integer fractions of (1,2,4 and 8) so it does not fit my application:

Hi olegeorg ,

I am checking on it. Yes, you are right we have limitation with device clock frequency multiple. As it is 9/10 ratio of Rx/Tx which is difficult to go further. 
one option we have is either use 2 different devices or do different combination of sample rate and implement the remaining rate match in the Host side.

Please find below snapshot from AD9371 GUI for the suitable combination
