What does "observation receiver" means?.
I want to know the difference between "receiver" and "observation receiver"
Observation path by design is intended to be used for Digital pre-distortion (DPD) feedback (observation) path . Detailed specification of ORx path is available in datasheet.
Major difference compared to receive (Rx) are ,
In the ADRV909 data sheet (Rev A) the datapath filter look the same (page 98, figure 431 vs 432) for Rx and Ox. It shows a block for digital gain in both datapathes.
Is the limitation (your 1. - 5.) due to performance of ARM M3 CPU and ADC? In other words: is it possible to just use ORx in ADRV9008-2 to increase bandwidth compared to Rx in ADRV9008-1 and have less limitations, since CPU has enough time to just service ORx datapath?
