Transmit Data Input (TBI mode).
Transmit code-group data bit 9 is input on this pin synchro-
nously to the rising edge of PMATXCLK in TBI mode.
Multiplexed Transmit Data Input (RTBI mode).
Bit [4] is synchronously input on the rising edge of TXC, and
bit [9] on the falling edge of TXC.
Transmit Error Input (GMII, MII modes).
When asserted, this synchronous input causes error sym-
bols to be transmitted from the PHY when operating in
100Mb or 1000Mb modes.
Transmit Enable, Transmit Error Multiplexed Input
(RGMII mode).
In RGMII mode, this input is sampled by the PHY on oppo-
site edges of TXC to indicate two transmit conditions of the
MAC:
1) on the rising edge of TXC, this input serves as TXEN, indi-
cating valid data is available on the TD input data bus.
2) on the falling edge of TXC, this input signals a transmit
error from the MAC, based on a logical derivative of TXEN
and TXER, per RGMII specification Version 1.2a, Section
3.4.
PMA Transmit Code Group Clock Input (TBI mode).
125 MHz transmit code-group clock. This code-group clock
is used to latch data into the PMA (in this case, the PHY) for
transmission.
Transmit Clock Input (GMII mode).
The transmit clock GTXCLK is a 125MHz, +/-100ppm refer-
ence clock used to synchronize the TXD data code group,
TXD[7:0], into the PHY.
Transmit Clock Input (RGMII/RTBI mode).
The transmit clock shall be either a 125MHz or 25MHz (for
1000Mb or 100Mb modes, respectively), with a +/-50ppm tol-
erance.
