The “MAC IF Mode and RGMII Speed ($ Port_Index + 0x10)” on

 

 

page 167 determines the MAC operational frequency and mode for a

NOTE: Set the “Clock and Interface Mode Change Enable Ports 0 - 3

and RGMII

NOTE: The initialization sequence provided in Section 6.1, “Change Port Mode Initialization Sequence” on page 130 must be followed for proper configuration of the IXF1104 MAC.

5.1.4Fiber Mode

When the IXF1104 MAC is configured for fiber mode, the TX Data path from the MAC is an internal

10-bit interface as described in the IEEE 802.3z specification. It is connected directly to an internal SerDes block for serialization/deserialization and transmission/reception on the fiber medium to and from the link partner.

The MAC contains all of the PCS (8B/10B encoding and 10B/8B decoding) required to encode and decode the data. The MAC also supports auto-negotiation per the IEEE 802.3z specification via access to the “TX Config Word ($ Port_Index + 0x17)", “RX Config Word ($ Port_Index + 0x16)", and “Diverse Config Write ($ Port_Index + 0x18)".
