Small Footprint MII/RMII 10/100 Ethernet Transceiver with HP Auto-MDIX and flexPWR® Technology
Datasheet
Note: Current measurements do not include power applied to the magnetics or the optional external
LEDs. The Ethernet component current is typically 41mA in 100BASE-TX mode and 100mA in
10BASE-T mode, independent of the 2.5V or 3.3V supply rail of the transformer.
Note 5.6 Calculated with full flexPWR features activated: VDDIO=1.8V & internal regulator disabled.

DC Specifications
Table 5.2 details the non-variable I/O buffer characteristics. These buffer types do not support variable
voltage operation. Table 5.3 details the variable voltage I/O buffer characteristics. Typical values are
provided for 1.8V, 2.5V, and 3.3V VDDIO cases.

Note 5.7 This specification applies to all inputs and tri-stated bi-directional pins. Internal pull-down
and pull-up resistors add +/- 50uA per-pin (typical).
Note 5.8 XTAL1/CLKIN can optionally be driven from a 25MHz single-ended clock oscillator.
