Product Number: ADRV9002
Hi,
The "ADRV9001 System Development User Guide" (Rev. A) lacks documentation on the use and timing for CPS (Channel power save) and SPS (System power save) when in Frequency (FH) (Frequency hopping) mode.
While trying out different approaches, I only manage to get SPS to work (have tried power down mode 4).
System test setup:
FH mode: Real Time LO Re-Tune.
Hop signal inactive (On the last edge of hop signal rx_setup and tx_setup where low).
Test1: If DGPIO4 and DGPIO5 are set up as CPS control signals - nothing changes if I set these high.
Test2: If DGPIO4 is set up as SPS control signal - power consumption drops if set high (Power down mode 4).
How can I get the system to enter power-down mode 2?
