IXF1104 Quad-Port 10/100/1000 Mbps Ethernet Media Access Controller

5.7Optical Module Interface

This section describes the connection of the IXF1104 ports to an Optical Module Interface and details the minimal connections that are supported for correct operation. The registers used for write control and read status information are documented.

The Optical Module Interface allows the IXF1104 a seamless connection to the Small Form Factor Optical Modules (SFP) that form the system’s physical media connection, eliminating the need for any FPGAs or CPUs to process data. All required optical module information is available to the system CPU through the IXF1104 CPU interface, leading to a more integrated, reliable, and cost- effective system.

The IXF1104 supports all the functions required for the Small Form Factor pluggable Multi-Source Agreement (MSA).

There are specific mechanical and electrical requirements for the size, form factor, and connections supported on all Optical Module Interfaces. There are also specific requirements for each Optical Module Interface that supports a particular media requirement or interface configuration. These requirements are detailed in the relevant specifications or manufacturers’ datasheets.

5.7.1IXF1104-Supported Optical Module Interface Signals

To describe the Optical Module Interface operation, three supported signal subgroups are required, allowing a more explicit definition of each function and implementation. The three subgroups are as follows:

•High-Speed Serial Interface

•Low-Speed Status Signaling Interface

•I²C Module Configuration Interface

Table 30 provides descriptions for IXF1104-to-SFP optical module connection signals.
