TX Error LED:
Indicates an error was detected by the TX Code Group
Alignment Monitor function on the TX receiver. Active
low (Open Drain Output)
The DM9301 incorporates a "monostable" function on
the TXERRLED output. This ensures that even
minimum size errors generate adequate LED ON to
insure visibility.
I
FX Interface Analog Loop Back:
Loops the FX NRZI analog transmit data path to the FX
NRZI analog receive path.
Initiated at a H/W reset. Active high.
I
TX Interface Analog Loop Back:
Loops the TX NRZI analog transmit data path to the TX
NRZI analog receive path.
Initiated at a H/W reset. Active high.
I
FX Interface Digital Loop Back:
Loops the FX 5-bit symbol digital transmit data path to
the FX 5-bit symbol digital receive path.
Initiated at a H/W reset. Active high.
I
TX Interface Digital Loop Back:
Loops the TX 5-bit symbol digital transmit data path to
the TX 5-bit symbol digital receive path.
Initiated at a H/W reset. Active high.
0
Receive Data 4 through 0:
The receive data 5-bit symbol interface. Data is clocked
out on the falling edge of RXCLK.
O
Receive Clock:
25 Mhz recovered clock, clock source is selected by the
MUXCTL1 and MUXCTL0.
I
Transmit Data 4 through 0:
The transmit data 5-bit symbol interface. Data is clocked
in on the rising edge of TXCLK.
O
Transmit Clock:
25 Mhz recovered clock, clock source is selected by the
MUXCTL1 and MUXCTL0.
