Pin Description
Pin Number
Pin Name
Type(1)
Pin Function
1
MDIO
I/O
Management Independent Interface (MII) Data I/O. This pin requires an external
10K pull-up resistor.
2
MDC
I
MII Clock Input. This pin is synchronous to the MDIO.
3
RXD3/
Ipd/O
MII Receive Data Output. RXD [3..0], these bits are synchronous with RXCLK.
PHYAD
When RXDV is asserted, RXD [3..0] presents valid data to MAC through the MII.
RXD [3..0] is invalid when RXDV is de-asserted.
During reset, the pull-up/pull-down value is latched as PHYADDR [1]. See
“Strapping Options” section for details.
4
RXD2/
Ipd/O
MII Receive Data Output.
PHYAD2
During reset, the pull-up/pull-down value is latched as PHYADDR[2]. See
“Strapping Options” section for details.
5
RXD1/
Ipd/O
MII Receive Data Output.
PHYAD3
During reset, the pull-up/pull-down value is latched as PHYADDR [3]. See
“Strapping Options” section for details.
6
RXD0/
Ipd/O
MII Receive Data Output.
PHYAD4
During reset, the pull-up/pull-down value is latched as PHYADDR [4]. See
“Strapping Options” section for details.
7
VDDIO
P
Digital IO 2.5 /3.3V tolerant power supply. 3.3V power Input of voltage
regulator. See “Circuit Design Ref. for Power Supply" section for details.
8
GND
Ground.
9
RXDV/
Ipd/O
MII Receive Data Valid Output.
CRSDV/
During reset, the pull-up/pull-down value is latched as PCS_LPBK. See
PCS_LPBK
“Strapping Options” section for details.
10
RXC
O
MII Receive Clock Output. Operating at 25MHz = 100Mbps, 2.5MHz = 10Mbps.
11
RXER/ISO
Ipd/O
MII Receive Error Output.
During reset, the pull-up/pull-down value is latched as ISOLATE during reset. See
“Strapping Options” section for details.
12
GND
Ground.
13
VDDC
P
Digital core 2.5V only power supply. See “Circuit Design Ref. for Power Supply"
section for details.
14
TXER
Ipd
MII Transmit Error Input.
15
TXC/
I/O
MII Transmit Clock Output.
REFCLK
Input for crystal or an external 50MHz clock. When REFCLK pin is used for
REF clock interface, pull up XI to VDDPLL 2.5V via 10k
resistor and leave
XO pin unconnected.
16
TXEN
Ipd
MII Transmit Enable Input.
17
TXD0
Ipd
MII Transmit Data Input.
18
TXD1
Ipd
MII Transmit Data Input.
Notes:
1. P = Power supply.
GND = Ground.
I = Input.
I/O = Bidirectional.
Ipd = Input w/ internal pull-down.
Ipd/O = Input w/ internal pull-down during reset, output pin otherwise.
Ipu = Input w/ internal pull-up.
Ipu/O = Input w/ internal pull-up during reset, output pin otherwise.
O = Output.
