UTOPIA Mode of Operation:
UTOPIA Transmit clock input. Also known as UTP_TX_CLK. This signal is used to synchronize all
UTOPIA transmit outputs to the rising edge of the UTP_OP_CLK.
MII Mode of Operation:
Externally supplied transmit clock.
SMII Mode of Operation:
Not Used.
When this interface/signal is enabled and is not being used in a system design, the interface/
signal should be pulled high with a 10-KΩ resistor.
UTOPIA flow control output signal. Also known as the TXENB_N signal.
Used to inform the selected PHY that data is being transmitted to the PHY. Placing the PHY’s
address on the UTP_OP_ADDR — and bringing UTP_OP_FCO to logic 1, during the current clock —
followed by the UTP_OP_FCO going to a logic 0, on the next clock cycle, selects which PHY is
active in MPHY mode.
In SPHY configurations, UTP_OP_FCO is used to inform the PHY that the processor is ready to
send data.
This signal must be tied to Vcc with an external 10-KΩ resistor.
Start of Cell. Also known as TX_SOC.
Active high signal is asserted when UTP_OP_DATA contains the first valid byte of a transmitted
cell.
This signal must be tied to Vss with an external 10-KΩ resistor.
UTOPIA Mode of Operation:
UTOPIA output data. Also known as UTP_TX_DATA. Used to send data from the
ATM UTOPIA Level 2-compliant PHY.
MII Mode of Operation:
Transmit data bus to PHY, asserted synchronously with respect to ETHA_TXCLK. This MAC
interface does not contain hardware hashing capabilities local to the interface. In this mode of
operation the pins represented by this interface are ETHA_TXDATA3:0].
SMII mode of operation:
Not used.
