Part Number: DP83848I
Hi Experts:
I found an issue when debugging the DP83848 .
There is different output waveform between them ,the output of LED_LINK and LED_SPEED will cause a fault in the firmware.
The below start up waveform of DP83848, the application is 100M.
The below start up waveform of KSZ8081MNXCA, the application is 100M.
As the description of d/s, the LED_LINK should be ON for good link and SPEED is ON for 100M, why the speed pin will be pulled low before the LED_LINK pulled low.
How can i make the same output waveform as the KSZ8081?
