hi
My customer is applying DP83848N.
I would like to know the absolute maximum ratings of 11,12 (RD +, RD-) pin and 14,15 (TD +, TD-) pin based on DP83848N.
I explained to the customer at the link below.
"Vin / Vout specifications are -0.5V to Vcc + 0.5V."
e2e.ti.com/.../840939
The problem is as follows:
DP83848N uses VCC 3.3V input.
That means no more than 3.8V input.
Absolute maximum value is too low.
Isn't the data sheet content wrong?
Like the picture below
When the PHY chip operates normally, the voltage of the corresponding MDI Pin will be about 4V as shown below. 3.8V doesn't make sense.
