DESCRIPTION
Output. 4 μsec clock used to shift data in
and out of the serial EEPROM.
Output. Serial EEPROM chip select.
Used for selection and command framing
of the serial EEPROM.
Output. Connected to the DI input of the
serial EEPROM.
Input. Connected to the DO output of the
serial EEPROM.
Input. External switches can be
connected to these lines to select
between predefined EEPROM
configurations.
Input. Enables (when high or open)
LAN91C111 accesses to the serial
EEPROM. Must be grounded if no
EEPROM is connected to the
LAN91C111.
An external 25 MHz crystal is connected
across these pins. If a TTL clock is
supplied instead, it should be connected
to XTAL1 and XTAL2 should be left open.
XTAL1 is the 5V tolerant input of the
internal amplifier and XTAL2 is the output
of the internal amplifier.
+3.3V Power supply pins.
+3.3V Analog power supply pins.
Ground pins.
Analog Ground pins
Output. Active when LOOP bit is set
(TCR bit 1).
Input. General-purpose input port used to
convey LINK status (EPHSR bit 14).
General Purpose Control Pin
25Mhz Output to external PHY
Output to MII PHY. Envelope to 100
Mbps transmission.
Input from MII PHY. Envelope of packet
reception used for deferral and backoff
purposes.
