100Mbps-TX Differential Input Pair:
These pins are differential receive input for 100BASE-
TX. They are capable of receiving 100BASE-TX MLT-3
data.
100BASE-TX Differential Output Pair:
These outputs drive MLT-3 encoded data over 100Mbps
twisted pair cable and provide controlled rise and fall
times designed to filter the transmitter
reducing any associated EMI.
100BASE-FX PECL Receive Data Differential Pair:
These pins are differential receive input for 100BASE-
FX PECL. They are capable of receiving PECL
100BASE-FX NRZI data.
100BASE-FX Transmit Differential Output Pair:
These outputs drive NRZI encoded data for PECL FX
interface.
100BASE-FX PECL Signal detect:
These pins are differential signals that indicate to the
DM9301 that the Optical Module interface is detecting
valid optical energy.

Crystal or Oscillator Input:
This pin should connect to one side of a 25MHz, 50ppm
crystal if OSC/XTL#=0. This pin is the 25MHz, 50ppm
external TTL oscillator input, if OSC/XTLB=1.
Crystal Oscillator Output:
The other side of a 25MHz, 50ppm crystal should
connect to this pin if OSC/XTL#=0. Leave this pin open
if OSC/XTL#=1.
Crystal or Oscillator Selector Pin:
OSC/XTL#=0: An external 25MHz, 50ppm crystal
should connect to X1 and X2 pins.
OSC/XTL#=1: An external 25MHz, 50ppm oscillator
should connect to X1 and left X2 pin
open.
Bandgap Voltage Reference Resistor:
It connects to a 6.49K
, 1% error tolerance resistor
between this pin and BGRET pin 9 to provide an
accurate current reference for the chip.
Bandgap Return
Return pin for 6.49K
resistor connection,
