DATASHEET
Carrier Sense: Indicates detection of carrier.
Receive Data Valid: Indicates that recovered and decoded data
nibbles are being presented on RXD[3:0].
Note:
LED1 – SPEED100 indication. Active indicates that the selected
speed is 100Mbps. Inactive indicates that the selected speed is
10Mbps.
Note:
LED2 – LINK ON indication. Active indicates that the Link
(100Base-TX or 10Base-T) is on.
Note:
LED3 – ACTIVITY indication. Active indicates that there is
Carrier sense (CRS) from the active PMD.
Note:
LED4 – DUPLEX indication. Active indicates that the PHY is in
full-duplex mode.
Note:
Management Data Input/OUTPUT: Serial management data
input/output.
Management Clock: Serial management clock.
PHY Address Bit 4: set the default address of the PHY. This
signal is mux’d with GPO1
PHY Address Bit 3: set the default address of the PHY.
Note:
PHY Address Bit 2: set the default address of the PHY.
Note:
PHY Address Bit 1: set the default address of the PHY.
Note:
PHY Address Bit 0: set the default address of the PHY.
Note:
