AD9361 - Digital loopback test

Hi,

I'm using AD-FMCOMMS3-EBZ mounted on ZC-706REV 1.2.

My discussion purpose is to figure out how the digital BIST lopback RX DLY adn TX DLY is being calibrated.


I'm reading for a few times reg 0x006 and 0x007 after EVB and AD9361 initilization.

For each time I'm receiving a different value (0x006 = 0x04, 0x05, 0x06)


I'm trying to duplicate the algorithm to my system.

I have the AD9361 with LVDS at max. rate (less than 500MHz).


Where can I find the algorithm? I have the following function of the EVB:

  • ad9361_bist_loopback
  • ad9361_bist_prbs
  • ad9361_hdl_loopback

Where can I find the FW for this EVB?

Is it possible to describe (block diagram or flow chart) how does Analog implemted it?


Thanks,

Idan Artom.
