Position of RSSI block in RxTSP diagram is inconsistent

Open Keno opened this issue 2 years ago • 1 comments

The diagram in A2.14 of the SPI reference seems to indicate that the RxTSP's digital RSSI samples the signal strength before the AGC block: image (6)

This is inconsistent with the following diagram in the main data sheet that indicates that RSSI is sampled after the gain is applied

Either mode of operation could make sense here, but it'd be good to be consistent in the diagrams.

Both diagrams are consistent. Just second diagram gives you more details about implementation. In the first diagram IQ data are fed to RSSI block. The same is in the second diagram, just follow the arrows (when AGC is in RSSI mode, multipliers are bypassed).
