Other Parts Discussed in Thread: MMWAVEICBOOST,
Hi,
In HW bringup guidelines sheet of HardwareDesignChecklist_V0p8_IWR6843.xlsx, it suggests customer to detect the voltage of VOUT_14APLL and VOUT_14SYNTH pins to see if they are both about 1.4V.
But I did some tests and found only in some condition, the output voltage of VOUT_14APLL and VOUT_14SYNTH pins both output 1.4V, such as after RF init in mode 2 and oob demo run in function mode.
Would you pls kindly advise if what I observed is as expected? If yes, would you pls update related info in checklist as it may confuse customer?

| IWR6843ISK+MMWAVEICBOOST | VOUT_14APLL | 0V | 1.38V | 1.38V | 1.38V |
| VOUT_14SYNTH | 0V | 1.43v | 0V | 1.43v | |
I have another question about VOUT_14APLL voltage in mode 2 after power on. Why It is 0V? Does it mean in mode 2 the APLL doesn't work or in bypass mode after power on?
