DATASHEET
Receive Data: 100Base-TX or 10Base-T differential receive
inputs from magnetics.
Receive Data: 100Base-TX or 10Base-T differential receive
inputs from magnetics.
Connects to reference resistor of value 12.4K-Ohm, 1%
connected as described in the Analog Layout Guidelines. The
nominal voltage is 1.2V and therefore the resistor will dissipate
approximately 1mW of power.
No Connect
+3.3V Analog Power
Analog Ground
+1.8V (Core voltage) - 1.8V for digital circuitry on chip. Supplied
by the on-chip regulator unless the regulator is disabled by
grounding the REG_EN pin. Place a 0.1uF capacitor near this
pin and connect the capacitor from this pin to ground. When
using the on-chip regulator, place a 4.7uF ±20% capacitor with
ESR < 1ohm near this pin and connect the capacitor from this
pin to ground. X5R or X7R ceramic capacitors are
recommended since they exhibit an ESR lower than 0.1ohm at
frequencies greater than 10kHz.
