(transceiver + digital I/O)
- Current consumption is for the single 3.3V supply KSZ8893MQL/MBL device only, and includes the 1.2V
- Each PHY port’s transformer consumes an additional 45mA @ 3.3V for 100BASE-TX and 70mA @ 3.3V
voltages (VDDA, VDDAP, VDDC) that are provided by the KSZ8893MQL/MBL via power output pin 22.
