Description
Transmit Clock: TXCLK is a continuous clock from PHY. It provides
the timing reference for the transfer of the TXEN and TXD[3:0]
signals from the MII port to the PHY.
Transmit Enable: TXEN is transition synchronously with respect to the
rising edge of TXCLK. TXEN indicates that the port is presenting
nibbles on TXD [3:0] for transmission.
68, 69, 70, 71 Transmit Data: TXD[3:0] is transition synchronously with respect to
the rising edge of TXCLK. For each TXCLK period in which TXEN is
asserted, TXD[3:0] are accepted for transmission by the PHY.
41
Collision: this signal is driven by PHY when collision is detected.
42
Carrier Sense: Asynchronous signal CRS is asserted by the PHY when
either transmit or receive medium is non-idle.
17
Receive Clock: RXCLK is a continuous clock that provides the timing
reference for the transfer of the RXDV and RXD[3:0] signals from the
PHY to the MII port.
19
Receive Data Valid: RXDV is driven by the PHY synchronously with
respect to RXCLK. Asserted high when valid data is present on RXD
[3:0].
29, 30, 31, 32 Receive Data: RXD[3:0] is driven by the PHY synchronously with
respect to RXCLK.
62
Station Management Data Clock: The timing reference for MDIO. All
data transfers on MDIO are synchronized to the rising edge of this
clock.
63
Station Management Data Input/Output: Serial data input/output
transfers from/to the PHYs.
