Intel® IXF1104 4-Port Gigabit Ethernet Media Access Controller

5.7.2.2.2TX_FAULT_0:3

TX_FAULT_0:3 are inputs to the IXF1104 MAC. These signals are pulled to a logic Low level by the optical module during normal operation. A logic Low level on these signals indicates no fault condition exists. If a fault is present, a logic High is received through the use of an external pull-up resistor at the IXF1104 MAC pad.

The status of each bit (one for each port) can be found in bits [13:10] of the “Optical Module Status Ports 0-3 ($0x799)” on page 222. Any change in the state of these bits causes a logic Low level on the TX_FAULT_INT output if this operation is enabled.

5.7.2.2.3RX_LOS_0:3

RX_LOS_0:3 are inputs to the IXF1104 MAC. These signals are pulled to a logic Low level by the optical module during normal operation, which indicates that no loss-of-signal exists. If a loss-of- signal occurs, a logic High is received on these inputs through the use of an external pull-up resistor at the IXF1104 MAC device pad.

The status of each bit (one for each port) is found in “Optical Module Status Ports 0-3 ($0x799)" bits [23:20]. Any change in the state of these bits causes a logic Low level on the RX_LOS_INT output if this operation is enabled.

5.7.2.2.4TX_DISABLE_0:3

TX_DISABLE_0:3 are outputs from the IXF1104 MAC. These signals are driven to a logic Low level by the IXF1104 MAC during normal operation. This indicates that the optical module transmitter is enabled. If the optical module transmitter is disabled, this signal is switched to a logic High level. On the IXF1104 MAC, these outputs are open drain types and pulled up by the 4.7 k to 10 k pull-up resistor at the Optical Module Interface. Each of these signals is controlled through bits 3:0 respectively of the “Optical Module Control Ports 0 - 3 ($0x79A)".

5.7.2.2.5MOD_DEF_INT

MOD_DEF_INT is a single output, open-drain type signal and is active Low. A change in state of any MOD_DEF_0:3 inputs causes this signal to switch Low and remain in this state until a read of the “Optical Module Status Ports 0-3 ($0x799)". The signal then returns to an inactive state.

5.7.2.2.6TX_FAULT_INT

TX_FAULT_INT is a single output, open-drain type signal and is active Low. A change in state of any TX_FAULT_0:3 inputs causes this signal to switch Low and remain in this state until a read of the “Optical Module Status Ports 0-3 ($0x799)". The signal then returns to an inactive state.

5.7.2.2.7RX_LOS_INT

RX_LOS_INT is a single output, open-drain type signal and is active low. A change in state of any of the RX_LOS_3:0 inputs causes this signal to switch low and remain in this state until a Read of the “Optical Module Status Ports 0-3 ($0x799)" has taken place. The signal returns to an inactive state.

Note: MOD_DEF_INT, TX_FAULT_INT, and RX_LOS_INT are open-drain type outputs. With the three signals on the device, the system can decide which “Optical Module Status Ports 0-3
