							Datasheet
PIN NO.		NAME	SYMBOL		BUFFER		DESCRIPTION
					TYPE
TQFP	QFP
125	127	Receive Data	RX_DV		I with		Input from MII PHY. Envelope of data
		Valid			pulldown		valid reception. Used for receive data
							framing.
112	114	Collision Detect	COL100		I with		Input from MII PHY. Collision detection
		100 Mbps			pulldown		input.
113-116	115-118	Transmit Data	TXD3-		O12		Outputs. Transmit Data nibble to MII
			TXD0				PHY.
109	111	Transmit Clock	TX25		I with		Input. Transmit clock input from MII.
					pullup		Nibble rate clock (25MHz for 100Mbps &
							2.5MHz for 10Mbps).
118	120	Receive Clock	RX25		I with		Input. Receive clock input from MII PHY.
					pullup		Nibble rate clock. (25MHz for 100Mbps &
							2.5MHz for 10Mbps).
121-124	123-126	Receive Data	RXD3-		I with		Inputs. Received Data nibble from MII
			RXD0		pullup		PHY.
25	27	Management	MDI		I with		MII management data input.
		Data Input			pulldown
26	28	Management	MDO		O4		MII management data output.
		Data Output
27	29	Management	MCLK		O4		MII management clock.
		Clock
126	128	Receive Error	RX_ER		I with		Input. Indicates a code error detected by
					pulldown		PHY. Used by the LAN91C111 to discard
							the packet being received. The error
							indication reported for this event is the
							same as a bad CRC (Receive Status
							Word bit 13).
2	4	nChip Select	nCSOUT		O4		Output. Chip Select provided for
		Output					mapping of PHY functions into
							LAN91C111 decoded space. Active on
							accesses to LAN91C111’s eight lower
							addresses when the BANK SELECTED is
							7.
12	14	External	RBIAS		NA		Transmit Current Set. An external
		Resistor					resistor connected between this pin and
							GND will set the output current for the TP
							transmit outputs
14	16		TPO+		O/I		Twisted Pair Transmit Output, Positive.
15	17		TPO-		O/I		Twisted Pair Transmit Output, Negative
17	19		TPI+		I/O		Twisted Pair Receive Input, Positive
18	20		TPI-		I/O		Twisted Pair Receive Input, Negative.
22	24		nLEDA		OD24		PHY LED Output
23	25		nLEDB		OD24		PHY LED Output
	Note 5.1 If the EEPROM is enabled.
