Crystal inputs. To be connected to a 25MHz crystal with 50ppm accuracy
The differentials receive inputs of 100BASE-TX or 10BASE-T, these pins
directly input from Magnetic.
The differential Transmit outputs of 100BASE-TX or 10BASE-T, these pins
directly output to Magnetic.
Reference Bias Resistor. To be tied to an external 10.0K (1%) resistor which
should be connected to the analog ground at the other end.

LED DISPLAY & MISCELLANEOUS
102 Led-Act
O 4Leds mode: LED display for Activity status. This pin will be driven on with
10 Hz blinking frequency when either effective receiving or transmitting is
(Led-lnk/act)
detected.
(3Led mode): LED display for link and activity status. This pin will be
driven on continually when a good Link test is detected. This pin will be
driven on with 10 Hz blinking frequency when either effective receiving or
transmitting is detected.
103 Led-10Lnk O 4Leds mode: LED display for 10M b/s speed. This pin will be driven on
(Led-fd/col)
continually when the 10M b/s network operating speed is detected.
(3Leds mode): LED display for Full Duplex or Collision status. This pin will be
driven on continually when a full duplex configuration is detected. This pin
