I/O
QSPI Synchronous
Serial Output
QSPI_DOUT Provides the serial data from the QSPI and can be programmed to be
driven on the rising or falling edge of QSPI_CLK.
O
QSPI Synchronous
Serial Data Input
QSPI_DIN
Provides the serial data to the QSPI and can be programmed to be
sampled on the rising or falling edge of QSPI_CLK.
I
QSPI Serial Clock
QSPI_CLK
Provides the serial clock from the QSPI. The polarity and phase of
QSPI_CLK are programmable.
O
Synchronous Peripheral
Chip Selects
QSPI_CS[3:0] QSPI peripheral chip selects that can be programmed to be active
high or low.

Function
I/O
Twisted Pair Input +
RXP
Differential Ethernet twisted-pair input pin. This pin is high-impedance
out of reset.
I
Twisted Pair Input -
RXN
Differential Ethernet twisted-pair input pin. This pin is high-impedance
out of reset.
I
Twisted Pair Output +
TXN
Differential Ethernet twisted-pair output pin. This pin is
high-impedance out of reset.
O
Twisted Pair Output -
TXP
Differential Ethernet twisted-pair output pin. This pin is
high-impedance out of reset.
O
Bias Control Resistor
RBIAS
Connect a 12.4 k
Ω
(1.0%) external resistor, RBIAS, between the
PHY_RBIAS pin and analog ground.
Place this resistor as near to the chip pin as possible. Stray
capacitance must be kept to less than 10 pF
(>50 pF will cause instability). No high-speed signals can be permitted
in the region of RBIAS.
I
Activity LED
ACT_LED
Indicates when the EPHY is transmitting or receiving
O
Link LED
LINK_LED
Indicates when the EPHY has a valid link
O
Speed LED
SPD_LED
Indicates the speed of the EPHY connection
O
Duplex LED
DUPLED
Indicates the duplex (full or half) of the EPHY connection
O
Collision LED
COLLED
Indicates if the EPHY detects a collision
O
Transmit LED
TXLED
Indicates if the EPHY is transmitting
O
Receive LED
RXLED
Indicates if the EPHY is receiving
O
