Hello,
I have two questions about LMK05318B as below.
1.I checked that the lmk05318B on our system board is sometimes stuck in the POR process. We believe that our system is following the POR setup sequence (Figure 9-32) in the datasheet well. What can cause the device to no longer set registers after POR? For lmk05318b on our board, 3.3V for VDD Core and 1.8V for VDDO_x are applied, and SPI interface is used and PDN is in a float state. And this issue didn't happen on all boards, just a few boards.
2. After power is applied to the LMK05318B, I set the device using SPI and confirmed that the setting was successful. Then I tried to reconfigure the device using PDN pin (Low --> High). But it got stuck and I couldn't set anything further. I wonder if it is possible to hardware reset the device using the PDN pin without a power restart.
Thanks,
