Dear support team,
I have a customer to raise a external LNA control question.
In the NO OS driver inital code. There are below items.
In customer design, LNA is 12dB gain when enable, 8dB loss when bypass. Using GPIO0/1 to control LNA bypass or disable.
One question is what is mean for
//elna_gaintable_all_index_enable *** adi,elna-gaintable-all-index-enable
If set to 1, what does it mean? Will AD9361 will turn on LNA (GPIO is high) no matter the gain index is setting?
