Part Number: DP83848J
a customer of mine is currently using the DP83848JSQ in a design; however the device repeatedly gets damaged in the application. What they have been able to notice is that PIN 28 (REF_CLK Eingang) gets damaged (on the hardware) and they also see some shorts between VCC and GND.
contrary to what is written in the datasheet (see image below), they have a 4.7kOhm pull-up resistor in MODE Select. The device is supposed to be used in RMII mode:
thanks for your support.
I would recommend following that datasheet values. It is difficult to characterize the IC for values outside of the datasheet. The PHY might be entering a non-deterministic mode. However, its difficult to say if this can cause damage to the part or not. Can you ask customer to change the strap resistor values to match the datasheet values and check again.
We are glad that we were able to resolve this issue, and will now proceed to close this thread.

In reply to Aniruddha Khadye:
thanks for your response. i've let the customer know and they will try the 2.2kOhm as recommended in the datasheet.
