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 4.7K
pull-up resistor.
2
MDC
I
MII Clock Input. This pin is synchronous to the MDIO.
3
RXD3/
PHYAD
Ipd/O
MII Receive Data Output. RXD [3..0], these bits are synchronous with RXCLK.
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/
PHYAD2
Ipd/O
MII Receive Data Output.
During reset, the pull-up/pull-down value is latched as PHYADDR[2]. See “Strapping
Options” section for details.
5
RXD1/
PHYAD3
Ipd/O
MII Receive Data Output.
During reset, the pull-up/pull-down value is latched as PHYADDR[3]. See “Strapping
Options” section for details.
6
RXD0/
PHYAD4
Ipd/O
MII Receive Data Output.
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
Gnd
Ground.
9
RXDV/
CRSDV/
PCS_LPBK
Ipd/O
MII Receive Data Valid Output.
During reset, the pull-up/pull-down value is latched as PCS_LPBK. See “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
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/
REFCLK
I/O
MII Transmit Clock Output.
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.
19
TXD2
Ipd
MII Transmit Data Input.
20
TXD3
Ipd
MII Transmit Data Input.
21
COL/
RMII
Ipd/O
MII Collision Detect Output.
During reset, the pull-up/pull-down value is latched as RMII select. See “Strapping
Options” section for details.
22
CRS/
RMII_BTB
Ipd/O
MII Carrier Sense Output.
During reset, the pull-up/pull-down value is latched as RMII back-to-back mode when
RMII mode is selected. See “Strapping Options” section for details.
23
GND
Gnd
Ground.
