Type
Transmit UTOPIA Clock: This clock is used for the
transmit UTOPIA interface. The data and control signals
are transferred on the rising edge of this clock. Maxi-
mum clock frequency is 50 MHz.
UTOPIA Standard notation: TxClk
Transmit PHY Address Bus: In multi-PHY mode,
these leads indicate the address of the PHY being
selected and polled. Note that the null-PHY address is
not responded to. In single-PHY mode, this address is
not used and these leads must be tied to VSS.
UTOPIA Standard notation: TxAddr[4:0]
Transmit Cell Data Bus: Data input, valid when PPUT-
TXENB is asserted low.
In 8-bit data mode, only PPUTTXDATA[7:0] are used,
and PPUTTXDATA[15:8] must be tied to VSS.
UTOPIA Standard notation: TxData[15:0]
Transmit Bus Parity: Odd or even parity over data, or
data and control signals. Evaluated only when PPUT-
TXENB is asserted low.
UTOPIA Standard notation: TxPrty
Transmit Start of Cell: Indicates the start of cell. Valid
only when PPUTTXENB is asserted low.
UTOPIA Standard notation: TxSOC
Transmit Write Enable (Active Low): Used along with
PPUTTXADDR to initiate writes to the Tx FIFOs. Selec-
tion phase when PPUTTXENB is asserted high and
transfer phase when PPUTTXENB is asserted low. Dur-
ing transfer phase PPUTTXADDR is used for polling.
UTOPIA Standard notation: TxEnb*
