Table 6-1 Pin Functions
PIN TYPE(1) DESCRIPTION
NAME HTQFP VQFN
MAC INTERFACES RGMII
TX_CLK 30 O MII TRANSMIT CLOCK: TX_CLK is a continuous clock signal driven by the PHY during 10 Mbps or 100 Mbps MII mode. TX_CLK clocks the data or error out of the MAC layer and into the PHY.
The TX_CLK clock frequency is 2.5 MHz in 10BASE-Te and 25 MHz in 100BASE-TX mode.
TX_D7 31 I, PD GMII TRANSMIT DATA Bit 7: This signal carries data from the MAC to the PHY in GMII mode. It is synchronous to the transmit clock GTX_CLK.
TX_D6 30 I, PD GMII TRANSMIT DATA Bit 6: This signal carries data from the MAC to the PHY in GMII mode. It is synchronous to the transmit clock GTX_CLK.
TX_D5 33 I, PD GMII TRANSMIT DATA Bit 5: This signal carries data from the MAC to the PHY in GMII mode. It is synchronous to the transmit clock GTX_CLK.
TX_D4 34 I, PD GMII TRANSMIT DATA Bit 4: This signal carries data from the MAC to the PHY in GMII mode. It is synchronous to the transmit clock GTX_CLK.
TX_D3 35 25 I, PD TRANSMIT DATA Bit 3: This signal carries data from the MAC to the PHY in GMII, RGMII, and MII modes. In GMII and RGMII modes, it is synchronous to the transmit clock GTX_CLK. In MII mode, it is synchronous to the transmit clock TX_CLK.
TX_D2 36 26 I, PD TRANSMIT DATA Bit 2: This signal carries data from the MAC to the PHY in GMII, RGMII, and MII modes. In GMII and RGMII modes, it is synchronous to the transmit clock GTX_CLK. In MII mode, it is synchronous to the transmit clock TX_CLK.
TX_D1 37 27 I, PD TRANSMIT DATA Bit 1: This signal carries data from the MAC to the PHY in GMII, RGMII, and MII modes. In GMII and RGMII modes, it is synchronous to the transmit clock GTX_CLK. In MII mode, it is synchronous to the transmit clock TX_CLK.
TX_D0 38 28 I, PD TRANSMIT DATA Bit 0: This signal carries data from the MAC to the PHY in GMII, RGMII, and MII modes. In GMII and RGMII modes, it is synchronous to the transmit clock GTX_CLK. In MII mode, it is synchronous to the transmit clock TX_CLK.
TX_ER 39 I, PD GMII TRANSMIT ERROR: This signal is used in GMII mode to force the PHY to transmit invalid symbols. The TX_ER signal is synchronous to the GMII transmit clock GTX_CLK.
In MII 4B nibble mode, assertion of Transmit Error by the controller causes the PHY to issue invalid symbols followed by Halt (H) symbols until deassertion occurs.
In GMII mode, assertion causes the PHY to emit one or more code-groups that are invalid data or delimiter in the transmitted frame.
GTX_CLK 40 29 I, PD GMII and RGMII TRANSMIT CLOCK: This continuous clock signal is sourced from the MAC layer to the PHY. Nominal frequency is 125 MHz.
RX_CLK 43 32 O RECEIVE CLOCK: Provides the recovered receive clocks for different modes of operation:
2.5 MHz in 10-Mbps mode.
25 MHz in 100-Mbps mode.
125 MHz in 1000-Mbps GMII and RGMII mode.
RX_D0 44 33 S, O, PD RECIEVE DATA Bit 0: This signal carries data from the PHY to the MAC in GMII, RGMII, and MII modes. It is synchronous to the receive clock RX_CLK.
RX_D1 45 34 O, PD RECIEVE DATA Bit 1: This signal carries data from the PHY to the MAC in GMII, RGMII, and MII modes. It is synchronous to the receive clock RX_CLK.
RX_D2 46 35 S, O, PD RECIEVE DATA Bit 2: This signal carries data from the PHY to the MAC in GMII, RGMII, and MII modes. It is synchronous to the receive clock RX_CLK.
RX_D3 47 36 O, PD RECIEVE DATA Bit 3: This signal carries data from the PHY to the MAC in GMII, RGMII, and MII modes. It is synchronous to the receive clock RX_CLK.
RX_D4 48 S, O, PD RECIEVE DATA Bit 4: This signal carries data from the PHY to the MAC in GMII mode. It is synchronous to the receive clock RX_CLK.

MANAGEMENT INTERFACE
MDC 20 16 I, PD MANAGEMENT DATA CLOCK: Synchronous clock to the MDIO serial management input/output data. This clock may be asynchronous to the MAC transmit and receive clocks. The maximum clock rate is 25MHz and no minimum.
MDIO 21 17 I/O MANAGEMENT DATA I/O: Bi-directional management instruction/data signal that may be sourced by the management station or the PHY. This pin requires pullup resistor. The IEEE specified resistor value is 1.5kΩ, but a 2.2kΩ is acceptable.
INT / PWDN 60 44 I/O, PU INTERRUPT / POWER DOWN:
The default function of this pin is POWER DOWN.
POWER DOWN: Asserting this signal low enables the Power Down mode of operation. In this mode, the device will power down and consume minimum power. Register access will be available through the Management Interface to configure and power up the device.
INTERRUPT: This pin may be programmed as an interrupt output instead of a Power down input. In this mode, Interrupts will be asserted low using this pin. When operating this pin as an interrupt, it is an open-drain architecture. Register access is required for the pin to be used as an interrupt mechanism. When operating this pin as an interrupt, an external 2.2kΩ connected to the VDDIO supply is recommended.
