AD9361/AD9364 Frame to clock ratio with 1R/1T and 2R/2T

Hi,

 

We are using the No-Os version of the driver and we verified that the datasheet for the 1R/1T and 2R/2T is not matching the RX Frame timing, We also tried to set the part by writing the CONF1-CONF2,CONF3 registers values for the AD9361/AD9364 but we always see the RX Frame being 2 clocks wide using ZC702 with FMCOMMS2/4.

 

How can we set the part to work as 1R/1T mode?

What should we expect from RX Frame?

 

How can we set the part to work as 2R/2T mode?

Clearly the datasheet shows wider RX Frame signal for 2R/2T mode but we are not seeing that but a 50% duty cycle (2 clock wide)

How the AD9361 understands which data should be for 2R/2T?

 

Regards,
