Tristate Digital Output Pins:
When set high, all digital output pins are set to high
impedance.
Reset: Active Low input that initializes the DM9301,
must be asserted low for 30msecs after VCC is stable.
Send Halt on no Link Condition:
Causes the DM9301 to Send out a Halt symbol to the
TX interface if no FX link active or send out a Halt
symbol to the FX interface if no TX link active.
Propagates a no-link condition to the Link Partner if 1,
Idle symbol if 0. Active high
Config A: Must be connected to GND
Config B: Must be connected to GND
FX Link LED:
Indicates Good Link status for 100Mbps FX operation.
Active low (Open Drain Output)
TX Link LED:
Indicates Good Link status for 100Mbps TX operation.
Active low (Open Drain Output)
FX Receive LED:
Indicates the presence of receive activity for 100Mbps
FX operation. Active low (Open Drain Output)
The DM9301 incorporates a "monostable" function on
the FXRCVLED output. This ensures that even
minimum size packets generate adequate LED ON to
insure visibility.
TX Receive LED:
Indicates the presence of receive activity for 100Mbps
TX operation. Active low (Open Drain Output)
The DM9301 incorporates a "monostable" function on
the TXRCVLED output. This ensures that even
minimum size packets generate adequate LED ON to
insure visibility.
FX Error LED:
Indicates an error was detected by the FX Code Group
Alignment Monitor function on the FX receiver. Active
low (Open Drain Output)
The DM9301 incorporates a "monostable" function on
the FXERRLED output. This ensures that even
minimum size errors generate adequate LED ON to
insure visibility.
