Pin Description
USB Interface
USB 2.0 data positive pin.
USB 2.0 data negative pin.
USB 1.1 data positive pin. Please connect to DP through a 39ohm
(+/-1%) serial resistor.
USB 1.1 data negative pin. Please connect to DM through a 39ohm
(+/-1%) serial resistor.
VBUS pin input. Please connect to USB bus power.
12Mhz crystal or oscillator clock input. This clock is needed for USB
PHY transceiver to operate.
12Mhz crystal or oscillator clock output.
For USB PHY’s internal biasing. Please connect to AGND through a
12.1Kohm (+/-1%) resistor.
For USB PHY’s internal biasing. Please connect to AVDD3 (3.3V)
through a 1.5Kohm (+/-5%) resistor.
Station Management Interface
Station Management Data Clock output. The timing reference for
MDIO. All data transfers on MDIO are synchronized to the rising edge
of this clock. The frequency of MDC is 1.5MHz.
Station Management Data Input/Output. Serial data input/output
transfers from/to the PHYs. The transfer protocol conforms to the
IEEE 802.3u MII spec.
Station Management Interrupt input.
MII/GMII/RGMII Interface
Receive Clock. RX_CLK is received from PHY to provide timing
reference for the transfer of RXD [7:0], RX_DV, and RX_ER signals
on receive direction of MII/GMII/RGMII interface.

105
Receive Data Valid. RX_DV is driven synchronously with respect to
RX_CLK by PHY. It is asserted high when valid data is present on
RXD [7:0]. In RGMII mode, RX_DV acts as RX_CTL.
106
Receive Error. RX_ER is driven synchronously with respect to
RX_CLK by PHY. It is asserted high for one or more RX_CLK
periods to indicate to the MAC that an error has detected.
116
Collision Detected. COL is driven high by PHY when the collision is
detected.
115
Carrier Sense. CRS is asserted high asynchronously by the PHY when
either transmit or receive medium is non-idle.
