Input. When low the LAN91C96 is configured for 16 bit
bus operation. If left open the LAN91C96 works in 8 bit
bus mode. 16 bit configuration can also be
programmed via serial EEPROM or software
initialization of the CONFIGURATION REGISTER.
An external parallel resonance 20MHz crystal should
be connected across these pins. If an external clock
source is used, it should be connected to this pin
(XTAL1) and XTAL2 should be left open.
An external parallel resonance 20MHz crystal should
be connected across these pins. If an external clock
source is used, it should be connected to XTAL1 and
this pin (XTAL2) should be left open.
AUI receive differential inputs.
INTERNAL ENDEC - (nXENDEC pin open). In this
mode TXP and TXN are the AUI transmit differential
outputs. They must be externally pulled up using 150
ohm resistors.
EXTERNAL ENDEC - (nXENDEC pin tied low). In this
mode the pins are inputs used for collision and carrier
sense functions.
AUI collision differential inputs. A collision is indicated
by a 10MHz signal at this input pair.
10BASE-T receive differential inputs.
INTERNAL ENDEC - 10BASE-T transmit differential
outputs.
10BASE-T delayed transmit differential outputs. Used
in combination with TPETXP and TPETXN to generate
the 10BASE-T transmit pre-distortion.
INTERNAL ENDEC - Powerdown input. It keeps the
LAN91C96 in powerdown mode when high (open).
Must be low for normal operation.
EXTERNAL ENDEC - Transmit clock input from
external ENDEC.
A resistor should be connected between this pin and
analog ground to determine the receive threshold
voltage of TX Receive, AUI Receive, AUI Collision
Receive, and AUI transmit voltage.
When tied low the LAN91C96 is configured for
EXTERNAL ENDEC. When tied high or left open the
LAN91C96 will use its internal encoder/decoder.
