5.7.2Functional Descriptions

5.7.2.1High-Speed Serial Interface

These signals are responsible for transfer of the actual data at 1.25 Gbps. Table 41 “Intel® IXF1104 MAC DC Specifications” on page 133 shows the data is 8B/10B encoded and transmitted differentially.

The following signals are required to implement the high-speed serial interface:

TX_P_0:3

TX_N_0:3

RX_P_0:3

RX_N_0:3

5.7.2.2Low-Speed Status Signaling Interface

The following Low-Speed signals indicate the state of the line through the Optical Module Interface:

MOD_DEF_0:3

TX_FAULT_0:3

RX_LOS_0:3

TX_DISABLE_0:3

MOD_DEF_INT

TX_FAULT_INT

RX_LOS_INT

5.7.2.2.1MOD_DEF_0:3

MOD_DEF_0:3 are direct inputs to the IXF1104 and are pulled to a logic Low level during normal operation, indicating that a module is present for each channel respectively. If a module is not present, a logic High is received, which is achieved by an external pull-up resistor at the IXF1104 device pad.
