Tool/software:
Hi Teams:
When the PHY chip is powered down, the RXD0~RXD4 and RX_CTRL pins output a short 125MHz square wave signal. We have tested and found that the VDD3.3V, VDD1.0V, as well as the IO power and sleep power are all stable during this time. The waveform is shown in the figure below. Could you please help identify the cause of this issue?
Best Wishes!
