Notes:
1. Exceeding the absolute maximum rating may damage the device. Stresses greater than the absolute maximum rating may cause permanent
damage to the device. Operation of the device at these or any other conditions above those specified in the operating sections of this specification
is not implied. Maximum conditions for extended periods may affect reliability.
2. The device is not guaranteed to function outside its operating rating.
3. Devices are ESD sensitive. Handling precautions recommended. Human body model, 1.5k in series with 100pF.
4. TA = 25°C. Specification for packaged product only.
5. Current consumption is for the single 3.3V supply KSZ8041NL device only, and includes the 1.8V supply voltage (VDDPLL_1.8) that is provided by the
KSZ8041NL. The PHY port’s transformer consumes an additional 45mA @ 3.3V for 100Base-TX and 70mA @ 3.3V for 10Base-T.
